  https://www.ncbi.nlm.nih.gov/books/NBK610689/

  Sebaceous carcinoma is an uncommon and aggressive epithelial malignancy involving the sebaceous gland. While this malignancy is predominant in the head and neck region, it represents a rare malignant skin adnexal tumor typically observed in individuals in their 7th decade of life. […] These rare adnexal tumors, commonly misdiagnosed as chalazion, blepharitis, or nevus, are fast-growing and may lead to distant metastasis. […] Despite the reduced recurrence and metastatic rates, sebaceous carcinoma still has a high mortality and poor prognosis rate. A quicker and more accurate diagnosis can improve patient outcomes. […] Sebaceous carcinoma manifests as yellow, pink, or red firm nodules of varying sizes in extraocular presentations. Unlike the periocular subtype, the clinical features of extraocular neoplasms are nonspecific. Extraocular sebaceous carcinoma primarily localizes to the head and neck, followed by the trunk, salivary glands, genitalia, breast, ear canal, and oral cavity.

  Sebaceous carcinoma arises from the glands within the eyelids, caruncle or eyebrow. They are more commonly found on the upper eyelid and in middle-aged patients. […] Sebaceous cell carcinoma is suspected due to evidence of eyelash loss and the formation of a yellow-nodule. This tumor can also present as a persistent (months) non-responsive blepharitis or conjunctivitis. In these cases, a high index of suspicion for sebaceous cell carcinoma will lead to biopsy and the diagnosis. Once sebaceous carcinoma is suspected a biopsy is warranted. Before surgery, the pathologist should be advised of this possible diagnosis so the specimen can be processed appropriately. […] Sebaceous carcinomas are one of the rarest eye cancers and can look like a chalazion (stye) or conjunctivitis. In that sebaceous carcinoma can mimic these relatively benign diseases, eye care specialists should be suspicious of this tumor in any patient with persistent conjunctivitis, blepharoconjunctivitis or chronic/recurrent chalazion. Therefore, any conjunctivitis or chalazion that is not getting better after 3 months of observation, should be biopsied.

  Sebaceous carcinoma is a rare aggressive skin cancer arising from a sebaceous gland. […] The clinical presentation of extraocular lesions is as a non-specific tumour; they typically appear as a pink to a yellow-red nodule of varying sizes. […] As the carcinoma grows it may spread onto the conjunctiva, where it can be mistaken for keratoconjunctivitis or blepharoconjunctivitis. […] In advanced cases, the spread of the lesion may lead to both upper and lower lid lesions and cause loss of eyelashes (madarosis), ulceration, and distorted vision. […] Undiagnosed or late diagnoses can result in metastases (spread) to lymph nodes and parotid glands. […] Delayed diagnosis – diagnosis of periocular sebaceous carcinoma is often delayed by months to years (mean 13 years). […] Sebaceous carcinoma is an aggressive and potentially dangerous tumour that can lead to significant morbidity and mortality. The overall mortality rate is 510% because of inherent tumour factors, or delayed diagnosis and treatment. […] Factors for a poorer prognosis include delay in diagnosis of greater than 6 months, tumour diameter greater than 1 cm, and both upper and lower eyelid involvement.

  Sebaceous carcinoma is a rare, highly aggressive and lethal malignancy with a predilection for the periocular region. Most commonly, it involves meibomian glands of eyelids, leading to the terminology meibomian gland carcinoma. Other sebaceous gland-containing structures such as the caruncle, the glands of Zeis, and the eyebrows might possibly be involved. […] It requires a high index of suspicion to diagnose sebaceous cell carcinoma of the eyelid. The upper eyelid margins of elderly women in their seventies are principally involved. […] Both history and clinical features of this aggressive and lethal tumour are highly variable. More than half of sebaceous cell carcinomas resemble benign inflammatory conditions such as chalazion, blepharoconjunctivitis, keratitis or other malignant and benign skin lesions, often leading to a misdiagnosis or a missed diagnosis. Hence, any unilateral blepharoconjunctivitis with loss of eyelashes, thickening of the lid margin and that fails to respond to the treatment requires a biopsy.

  Sebaceous carcinoma is most frequently found in the head and neck region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, accounts for up to 75% of SGc cases. Periocular SGc typically presents as a yellow, hard, painless nodule or papule that may be mistaken for inflammatory conditions like chalazion or conjunctivitis. […] Extraocular SGc, comprising about 25% of all SGc, usually presents as a painless, red and brown or red and yellow, ulcerated papule on the head or neck, potentially mimicking nonmelanoma skin cancers or benign lesions like molluscum contagiosum. […] Survival rates are higher for ocular versus extraocular tumours and localised versus regional disease. The relative survival rates at 5 and 10 years are 92.72% and 86.98%, respectively. The rate of metastasis is approximately 4.4% for periocular SGc and 1.4% for extraocular SGc. Early recognition and improved treatment modalities have contributed to better prognosis over time.

• #57 Sebaceous carcinoma: an updated review of pathogenesis, diagnosis, and treatment options – PubMed

  https://pubmed.ncbi.nlm.nih.gov/38112896/

  Sebaceous carcinoma (SC) is a very rare and aggressive form of skin cancer that arises from the sebaceous glands. SC can occur anywhere on the body, but most commonly affects the head and neck, especially the upper eyelid. SC is the third most common malignancy of the eyelid and has the potential to metastasize and be fatal; therefore, it is vital for dermatologists to remain acquainted with this malignancy and its most current treatment options. Most commonly presenting as a painless lump or thickening of skin on the eyelid, SC has an insidious progression that may not prompt the patient to seek medical attention immediately. […] To avoid the potential of metastasis, early diagnosis and treatment is paramount. […] The prognosis of SC depends on several factors, including size, location, stage, and treatment method. After treatment of the neoplasm, diligent post-treatment surveillance remains the cornerstone of patient care. Continued dermatologic follow-ups are essential for early detection of reoccurrence, ensuring timely intervention and optimal long-term outcomes.

  Standard systemic treatments are not consistently effective for treating unresectable or advanced sebaceous carcinoma (SC). […] The present results suggested that hormonal and metabolic dysregulation may be associated with the pathogenesis of SC, and that AR and MCT1 in particular may serve as prognostic indicators and potential therapeutic targets. […] In the multivariate analysis, advanced stage, low AR positivity and high MCT1 expression were independent poor prognostic factors for metastasis-free survival (all P<0.05). [...] Significant differences were found in the T category and stage, with the disease progression group exhibiting higher T and advanced-stage tumors (P=0.012 and P=0.001, respectively).

  Sebaceous carcinoma is most frequently found in the head and neck region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, accounts for up to 75% of SGc cases. Periocular SGc typically presents as a yellow, hard, painless nodule or papule that may be mistaken for inflammatory conditions like chalazion or conjunctivitis. […] Extraocular SGc, comprising about 25% of all SGc, usually presents as a painless, red and brown or red and yellow, ulcerated papule on the head or neck, potentially mimicking nonmelanoma skin cancers or benign lesions like molluscum contagiosum. […] Survival rates are higher for ocular versus extraocular tumours and localised versus regional disease. The relative survival rates at 5 and 10 years are 92.72% and 86.98%, respectively. The rate of metastasis is approximately 4.4% for periocular SGc and 1.4% for extraocular SGc. Early recognition and improved treatment modalities have contributed to better prognosis over time.

  https://www.ncbi.nlm.nih.gov/books/NBK610689/

  Sebaceous carcinoma is an uncommon and aggressive epithelial malignancy involving the sebaceous gland. While this malignancy is predominant in the head and neck region, it represents a rare malignant skin adnexal tumor typically observed in individuals in their 7th decade of life. […] These rare adnexal tumors, commonly misdiagnosed as chalazion, blepharitis, or nevus, are fast-growing and may lead to distant metastasis. […] Despite the reduced recurrence and metastatic rates, sebaceous carcinoma still has a high mortality and poor prognosis rate. A quicker and more accurate diagnosis can improve patient outcomes. […] Sebaceous carcinoma manifests as yellow, pink, or red firm nodules of varying sizes in extraocular presentations. Unlike the periocular subtype, the clinical features of extraocular neoplasms are nonspecific. Extraocular sebaceous carcinoma primarily localizes to the head and neck, followed by the trunk, salivary glands, genitalia, breast, ear canal, and oral cavity.

  Sebaceous carcinoma is a rare, highly aggressive and lethal malignancy with a predilection for the periocular region. Most commonly, it involves meibomian glands of eyelids, leading to the terminology meibomian gland carcinoma. Other sebaceous gland-containing structures such as the caruncle, the glands of Zeis, and the eyebrows might possibly be involved. […] It requires a high index of suspicion to diagnose sebaceous cell carcinoma of the eyelid. The upper eyelid margins of elderly women in their seventies are principally involved. […] Both history and clinical features of this aggressive and lethal tumour are highly variable. More than half of sebaceous cell carcinomas resemble benign inflammatory conditions such as chalazion, blepharoconjunctivitis, keratitis or other malignant and benign skin lesions, often leading to a misdiagnosis or a missed diagnosis. Hence, any unilateral blepharoconjunctivitis with loss of eyelashes, thickening of the lid margin and that fails to respond to the treatment requires a biopsy.

  Sebaceous carcinoma arises from the glands within the eyelids, caruncle or eyebrow. They are more commonly found on the upper eyelid and in middle-aged patients. […] Sebaceous cell carcinoma is suspected due to evidence of eyelash loss and the formation of a yellow-nodule. This tumor can also present as a persistent (months) non-responsive blepharitis or conjunctivitis. In these cases, a high index of suspicion for sebaceous cell carcinoma will lead to biopsy and the diagnosis. Once sebaceous carcinoma is suspected a biopsy is warranted. Before surgery, the pathologist should be advised of this possible diagnosis so the specimen can be processed appropriately. […] Sebaceous carcinomas are one of the rarest eye cancers and can look like a chalazion (stye) or conjunctivitis. In that sebaceous carcinoma can mimic these relatively benign diseases, eye care specialists should be suspicious of this tumor in any patient with persistent conjunctivitis, blepharoconjunctivitis or chronic/recurrent chalazion. Therefore, any conjunctivitis or chalazion that is not getting better after 3 months of observation, should be biopsied.

[…] A characteristic feature of sebaceous cell carcinoma is the way it infiltrates. Intraepithelial spread or pagetoid spread is reported in 44-80% of cases. […] Since the presentation of sebaceous cell carcinoma is so varied, the differential diagnosis is broad including many distinct disease processes. […] The masquerading feature of sebaceous carcinoma makes it a difficult diagnosis. […] The frequency of wrong clinical impressions has remained unchanged for the last few decades. […] There are some clues in history and physical that help raise clinical suspicion.

  Sebaceous carcinoma (SC) is a very rare and aggressive form of skin cancer that arises from the sebaceous glands. SC can occur anywhere on the body, but most commonly affects the head and neck, especially the upper eyelid. SC is the third most common malignancy of the eyelid and has the potential to metastasize and be fatal; therefore, it is vital for dermatologists to remain acquainted with this malignancy and its most current treatment options. Most commonly presenting as a painless lump or thickening of skin on the eyelid, SC has an insidious progression that may not prompt the patient to seek medical attention immediately. […] To avoid the potential of metastasis, early diagnosis and treatment is paramount. […] The prognosis of SC depends on several factors, including size, location, stage, and treatment method. After treatment of the neoplasm, diligent post-treatment surveillance remains the cornerstone of patient care.
