BACKGROUND Becker nevus is a nevoid melanosis, referred to as Becker nevus syndrome when it is associated with other anomalies. Our objectives were to report the occurrence of a Becker nevus with an underlying desmoid soft-tissue tumor; to review Mayo Clinic's experience with Becker nevi, concentrating on Becker nevi associated with bone, vascular, neural, and other soft-tissue abnormalities; t...

Blue nevi are characterized by a collection of pigment-producing melanocytes in the dermis. These lesions clinically present as well demarcated cerulean-blue or bluish black colored papules or plaques that usually measure less than 1 cm in diameter. They are typically found on the dorsal surface of the hands and feet or in the head and neck region; however, they are rarely found in the oral cav...

PURPOSE To report adult cases of superior orbital apocrine hidrocystoma. METHODS Retrospective case series of three patients with superior orbital apocrine hidrocystoma and blepharoptosis with review of the clinical aspects of each of the cases. RESULTS All three cases presented with blepharoptosis. Two of the cases had occult hidrocystoma, and one was visibly subcutaneous at presentation. ...

Adnexal tumors (ATs) are primary skin tumors with benign or rarely, malignant behavior. They have been classified based on differentiation towards hair follicle, sebaceous, apocrine or eccrine gland. Few large-scale studies have focused on ATs. To determine the prevalence of ATs and to assess clinical and histopathological trend of ATs. A retrospective descriptive study of all ATs diagnosed in ...

Nevus depigmentosus is a stable and well-circumscribed congenital hypomelanosis that may be in an isolated, dermatomal or systemic form. An 18-yr-old Korean man with segmental nevus depigmentosus developed multiple pigmented nevi which were present only within the confines of the leukoderma. Histologic and electron microscopic studies rendered a diagnosis of nevus depigmentosus with dysplastic ...

A 63-year-old patient presented with a small painless nodular tumour of his left lower eyelid which had increased in size over the last few weeks. The tumour was excised by wedge resection and submitted for ophthalmopathologic examination. Histopathologic examination revealed a cystic lesion of apocrine origin with focal proliferations. The proliferative cells appeared pleomorphic and displayed...

Primary cutaneous apocrine gland carcinoma, which is a type of sweat gland carcinoma, is an extremely rare type of cancer. Clinical courses of this type of cancer usually progress slowly but can, occasionally, be associated with rapid progression. This case report describes a 53-year-old Korean man with primary cutaneous apocrine gland carcinoma that arose from an apocrine gland in the areola t...

Breast apocrine carcinoma is a rare malignancy characterized histologically by a predominance of acidophilic tumor cells exhibiting apocrine metaplasia. Apocrine tumors represent only about 0.4% of all breast cancers. Many cases are diagnosed at stage I or II; thus, the prognosis is better than that for other types of breast cancer. Here we present a 57-year-old female patient with primary apoc...

Studies surveying melanomas associated with melanocytic nevi in Asia are rare. In this study, we examined whether nevus-associated melanomas differ from de novo melanomas in terms of their associations with clinical factors, histologic characteristics, and patient survival in Taiwan. Using data on cancer cases obtained from the Department of Pathology archives and the Cancer Registry of Nationa...
