Syringoma is a benign adnexal tumor originated from the intraepidermal portion of eccrine sweat duct. They commonly present as soft, flesh colored to slightly yellow dermal papules on the lower eyelids of healthy individuals. It usually occurs in the peri-pubertal period. There are a few reports of its widespread distribution as eruptive syringoma in the literature. Treatment of this benign con...

A 61-year-old woman was diagnosed with rectal carcinoma. Colectomy and bilateral oophorectomy were performed. There was no peritoneal dissemination. Our case showed that colonic carcinoma coexisted with benign adnexal neoplasm. This fact suggests that the histogenesis of multiple benign or malignant tumors is likely to be secondary to an unexplained stimulus. Perhaps, the collection of cases wi...

We investigated the organization of the immunoglobulin heavy chain (IgH) and the T cell receptor beta chain (T beta) gene loci in 20 ocular adnexal and four extraocular lymphoid neoplasms obtained from 18 patients presenting with an ocular adnexal lymphoid neoplasm. Fifteen ocular adnexal and four extraocular lymphoid neoplasms occurring in 13 patients were classified by morphological examinati...

BACKGROUND Microcystic adnexal carcinoma, or sclerosing sweat duct carcinoma, is an uncommon cutaneous neoplasm associated with extensive local invasion. The standard of care with regard to the best excisional method in treating microcystic adnexal carcinoma has not been established. OBJECTIVES To perform a retrospective study comparing patients treated by Mohs micrographic surgery with those...

Syringocystadenoma papilliferum, a distinct dermatologic entity, is an exceedingly rare benign skin neoplasm and seems to have arisen from apocrine or eccrine adnexal structures. The diagnosis is clinically suspected and histologically confirmed due to its non presentations. Since it usually appears at birth or during puberty and adolescence, Childhood tumor. Complete surgical excision is the t...

An apocrine hidradenoma is a benign adnexal neoplasm, usually covered by intact skin, but may show superficial ulceration and serous discharge. This feature is raising the possibility of malignancy as it was in our case of macroscopically suspicious tumour. We described cytomorphologic features of cutaneous nodule that might be a lead to the cytologic diagnosis of hidradenoma, but primary or se...

Tumor of the follicular infundibulum is a rare benign cutaneous adnexal neoplasm with variable clinical presentation. In most cases the diagnosis is made with the help of histopathology, due to lack of a characteristic clinical presentation. The most common form is a solitary lesion, but it can be multiple or eruptive, then called infundibulomatose. This case report illustrates a patient with m...

Syringocystadenocarcinoma papilliferum (SCACP) is a very rare cutaneous adnexal neoplasm. SCACP presents histologic variability, and it is difficult to establish the diagnosis from a punch biopsy. SCACP has an overall configuration similar to that of syringocystadenoma papilliferum (SCAP). When we diagnose SCACP, the histologic features of SCAP can be contributing and immunohistochemical staini...

Poroma is a benign adnexal neoplasm with atn "poroid"/ductal differentiation that mimics benign and malignant skin tumors. Histopathology shows circumscribed proliferation of poroid cells intermingled with a variable number of cuticular cells. We report a case of pigmented poroma located on the face that simulated clinically and dermatoscopically a pigmented basal cell carcinoma. The features o...
