We herein report a case of hair follicle nevus, a rare hamartoma found on the face and showing follicular differentiation, which was associated with sebaceous hyperplasia. Dermoscopy of the lesion showed yellow globules surrounded by crown vessels/telangiectasias and scattered tiny hairs. Histopathological investigation revealed hyperplasia of the sebaceous glands and proliferation of well-diff...

This paper reports a rare case of sebaceous adenoma on the right mandibular retromolar mucosa in a 73-year-old Japanese man, with a review of the English literature of sebaceous adenomas of salivary gland origin. A painless and yellowish polypoid lesion in the retromolar mucosa was histologically a relatively well-circumscribed neoplastic mass composed of well-differentiated sebaceous cells wit...

Sebaceous lesions, including sebaceous hyperplasia, sebaceomas, and sebaceous adenomas and carcinomas, are histologically distinctive adnexal proliferations with a spectrum of biological behavior ranging from benign to frankly malignant. The histologic distinction between sebaceous adenomas and carcinomas may be challenging, especially in cases showing atypical features and in small or partial ...

composed of cells that exhibit sebaceous differentiation; these tumors account for less than 0.1% of all salivary gland neoplasms (1, 2). The parotid gland is the most frequently involved of the salivary glands, where sebaceous differentiation is common (3). There is little information available in English literature on the radiologic features of this rare neoplasm, especially that of cystic se...

Alopecia, accompanied by skin dryness, is one of the distressing side effects often occurring in chemotherapy-treated cancer patients. Little is known of the effects of chemotherapy on sebaceous glands, despite their importance in hair follicle homeostasis. This study investigates sebaceous gland morphology and the response of SZ95 sebaceous gland cell line to doxorubicin (DXR) treatment. The m...

Background. Cutaneous alterations are common in neonates. The majority of lesions are physiological, transient, or self-limited and require no therapy. Although much has been reported on the various disorders peculiar to the skin of infant, very little is known about variations and activity of the skin in neonates. Objective. To study the various pattern of skin lesions in newborn and to estima...

Sebaceous adenoma of the salivary gland is a rare tumor comprising 0.1% of all salivary gland neoplasms and less than 0.5% of salivary adenomas. Histologically, sebaceous adenomas are benign neoplasms consisting of sebaceous cells arranged in nests forming acinar and duct-like structures. Oncocytic metaplasia may also occur in some areas. We describe a case of sebaceous adenoma in the submandib...

the follicle arrangement and secondary to primary follicle ratio (s/p) were studied in the ‎skin of nine male and nine female markhoz goats breed from one week to 16 weeks of age. the ‎skin samples were taken from mid-side area of each animal in nine stages every other week. the ‎follicles were arranged in groups, predominantly including three primary and several ‎secondary follicles. each prim...

Muir-Torre syndrome (MTS), a subtype of Lynch syndrome II, presents as at least one internal malignancy associated with at least one sebaceous skin tumor. This autosomal-dominant genetic disorder is thought to arise from microsatellite instability. Although not all patients with sebaceous tumors have MTS, even a single biopsy-proven sebaceous adenoma may warrant evaluation for MTS. We report th...

Myoepitheliomas account for less than 1% of all salivary gland tumors and mostly occur in the parotid gland and palate. A 58-year old male patient reported to the Outpatient Department of PMS College of Dental Science and Research (Kerala, India) with a slow growing painless swelling on the palate for 4 years. Pleomorphic adenoma, basal cell adenoma, myoepithelioma, cyst adenoma, lipoma, neurof...
