BACKGROUND Sebaceous carcinoma of the eyelid is rare. The diagnosis might be difficult because of its ability to masquerade as other periocular lesions. Prognosis is still regarded as being poor compared with most other malignant eyelid tumours with a mortality second only to malignant melanoma. The present study retrospectively analyses clinical and histopathological findings and outcome in a ...

Primary sebaceous carcinoma of salivary glands is a rare entity with approximately 22 de novo documented cases. Similar tumor arising in a benign mixed tumor has only been reported once. We report a second case of sebaceous carcinoma in a pleomorphic adenoma and discuss the clinicopathologic features, histogenesis, and the differential diagnosis of this unusual tumor.

Reticulated acanthoma with sebaceous differentiation (RASD) is a rare, benign cutaneous tumor with peculiar histopathologic characteristics [1]. RASD had been described under various synonyms such as superficial epithelioma with sebaceous differentiation, sebocrine adenoma, poroma with sebaceous differentiation, and seborrheic keratosis with sebaceous differentiation [2]. Clinical differential ...

BACKGROUND: Sebaceous lymphadenoma is a rare benign salivary gland tumour of uncertain histogenesis. So is synchronous occurrence of two benign or malignant neoplasms. CASE-REPORT: 68-year-old female presented with right side parotid swelling associated with pain and gradual increase is size. Fine needle aspiration cytology of parotid swelling was suggestive of pleomorphic adenoma. Total conser...

Muir-Torre syndrome is a rare cancer predisposition syndrome characterized by unusual cutaneous tumors and internal malignancy. The cutaneous tumors associated with Muir-Torre syndrome include mainly sebaceous gland neoplasms (sebaceous adenoma and sebaceous carcinoma), keratoacanthoma, and basal cell carcinoma. Colorectal and genitourinary carcinoma are the common types of internal malignancie...

The expression of MUC1, Tn (GalNAc alpha 1-O-Ser/Thr) and sialosyl Tn (STn) (NeuAc alpha 2,6 GalNAc alpha 1-O-Ser/Thr) antigens, which are useful markers for the prognosis of cancer in other organs, was examined immunohistochemically in a series of 45 eyelid tumors and 5 pseudotumors: basal cell carcinoma, 18; squamous cell carcinoma, 11; sebaceous gland carcinoma, 6; seborrheic keratosis, 4; p...

431 ImageS nosis from basal cell carcinoma originating from the sebaceous gland. In the erythematous mass containing the nevus sebaceous, a wide excision was performed with a safety margin of 5 mm. A frozen section biopsy showed that there were no tumor cells on the resection margin. Following the resection, scalp defects of 2.5×5.0 cm in size remained (Fig. 2). The defects were reconstructed u...
