At their ¢rst studies on the physiology and pathophysiology of the skin looking for an adequate ¢eld of future dedication, budding skin researchers usually go quickly through the chapter on the Biology of Sebaceous Glands having obtained the following piece of knowledge: sebaceous glands produce sebum and are partially responsible for acne vulgaris. Seemingly, a limited and less attractive ¢eld...

Sebaceous adenomas of the major salivary glands are uncommon tumors. Although sebaceous differentiation within the major salivary glands is a frequent histopathologic finding (approximately 20% to 42% of parotid glands), sebaceous neoplasms of salivary gland origin are not. A number of publications review the clinical and histologic features of sebaceous neoplasms, however, these reports focus ...

We report a sebaceous carcinoma confined to the corneoscleral limbus without involvement of the eyelid. A 60-year-old man, who showed multiple masses on the corneaoscleral limbus and limbal ulceration but with normal eyelids, underwent surgical en-bloc excision of the masses. Histopathologic examination revealed a sebaceous carcinoma. Three weeks after excision, multiple pagetoid recurrences we...

Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently un...

BACKGROUND Intraoral sebaceous carcinoma is a rare form of sebaceous carcinoma with only 9 published cases in the world literature to date. We present a 10th case of intraoral sebaceous carcinoma located in the anterior maxillary gingiva with metastases to the lung and subcutis and discuss 3 possible etiologies for this unique presentation. METHODS We analyze the clinical presentation, pathol...

The study aimed to verify the therapeutic action of isotretinoin in the treatment of sebaceous hyperplasia. During two months, 20 patients with sebaceous hyperplasia took isotretinoin at a dosage of 1mg/kg per day. Their skin lesions were counted and photographed before and after treatment and re-evaluated two years later. The average number of sebaceous hyperplasia lesions before treatment was...

INTRODUCTION Sebaceous hyperplasia is associated with immunosuppressive treatment with cyclosporin in male renal transplant patients. This has not been reported in the local context. CLINICAL PICTURE This is a report on 2 Chinese renal transplant patients on cyclosporin who developed sebaceous hyperplasia. TREATMENT AND OUTCOME One patient was treated with carbon dioxide laser. The result w...

Sebaceous gland carcinomas (SGC) are highly malignant lid tumors which originate from meibomian glands and rarely from the gland of Zeis, sebaceous gland of caruncle, eyebrows and periocular skin. In many cases correct diagnosis of SGC is delayed because of its ability to masquerade as a variety of other ocular conditions. A forty year old male presented with a left upper eyelid swelling with a...

Pilomatrix carcinoma is a skin tumour about which there is a relative paucity of material in the plastic surgical literature. In the course of their practice most plastic surgeons will have come across the benign skin lesion designated "Clacifying Epithelioma o Malherbe" named thus in recognition of Malherbe\'s description of the entity in I 880, even though erroneously ascribed the tissue of o...
