sebaceous carcinoma is a relatively rare cutaneous tumor that is most commonly derived from the sebaceous glands located in periorbital area. the extraocular occurrence of this tumor is very rare. we report a case of an 85 years old woman who presented with a slowly enlarging mass on the right temporal region. histological examination of the lesion revealed a malignant sebaceous carcinoma occur...

Nevus sebaceous is a congenital, benign hamartomatous lesion, characterized by a yellowish to skin-colored, hairless, verrucous plaque on the head and neck region. In later life, a secondary tumor, either benign or malignant, can develop within nevus sebaceous. Eccrine poroma developing on nevus sebaceous is extremely rare. There are few case reports of eccrine poroma developing within nevus se...

The presentation herewith as scripted is to describe a case with Nevus sebaceous with oral manifestations. Nevus Sebaceous or Jadassohn's nevus is an epidermal nevus with predominant sebaceous glands seen histologically. Reports of oral involvement have been few ranging from papillomatous growths of the tongue, gingiva, palate to dental abnormalities such as anodontia and dysodontia. The presen...

Nevus sebaceous is known by its association with one or more secondary tumors, but more than three multiple tumors arising from a nevus sebaceous is extremely rare. A 67-year-old female presented with a light brown plaque on the back of her head that contained a dome-shaped black node and an erosive lesion. Histopathological examination showed atypical basaloid cells in the black node. At the p...

The predisposition to epithelial neoplasms in nevus sebaceous is well established; most tumors occur in adults and are benign. Hidradenoma is a relatively rare benign tumor of sweat gland origin that can rarely arise within a nevus sebaceous. We present an interesting case of a hidradenoma and sebaceoma arising within a nevus sebaceous and present a literature review of the 2 conditions. Even t...

Linear Nevus Sebaceous Syndrome (LNSS) is a rare sporadic oculoneurocutaneous disorder, also classified as Organoid Nevus Syndrome. It consists of a triad of midline facial linear nevus sebaceous, central nervous system and ocular abnormalities. To the best of authors' knowledge ophthalmic features of LNSS have never been reported in Pakistani population. We report two cases of LNSS, associated...

Syringocystadenoma papilliferum is an uncommon benign apocrine gland tumour, mostly of congenital or early childhood onset, affecting head and neck. In addition, nevus sebaceous is commonly associated with this tumor. Here, we document three cases of syringocystadenoma papilliferum with many atypical features, such as the involvement of rare sites (abdomen, axilla and thigh), absence of nevus s...

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...
