Fine needle aspiration cytology of eccrine skin adnexal tumors. The cells were arranged in lobules and ducts some of which contained eosinophilic secretion Inset, arrow H and E, x Papillary hidradenoka adenoma Eccrine carcinoma Eccrine nevus Syringofibroadenoma Spiradenoma. For example, acrospiroma and hidradenoma are synonymous, and sometimes the term acrospiroma is used to generally describe benign sweat gland tumors.
Dermatology Online Journal
Adnexal tumors need thorough histopathological analysis to conclude their biological behavior. The presence of melanocytes in sweat gland tumors is extremely rare because normal sweat glands lack melanocytes and melanin pigment.

N Am J Med Sci ;1: Few tubular lumina lined by cuboidal to round tumor cells containing eosinophilic material, pigment granules and pigment laden macrophages were also present.

Pigmented nodular hidradenoma masquerading as nodular malignant melanoma
On examination the swelling was fixed to skin, cystic on palpation and mildly tender Figure 1. This oncology article is a stub. A clinical impression of sebaceous cyst was given. Numerous pigment-containing dendritic melanocytes were present among these epithelial cells Fig. Case Report Open Access. J Cytol Histol ;2: Discussion of sweat gland tumors nosular be difficult and confusing due to the complex classification and nodulr terminology used to describe the same tumors.
Few lesions such as basal cell epithelioma, seborrheic keratosis, pseudoepitheliomatous hyperplasia, and even squamous cell carcinoma may show pigmentation from accompanying melanocytes [ 2 ].
Agri and Aquaculture Journals Dr. The prognosis is excellent following excision. The cells were chiefly eosinophilic with a regular oval grooved nucleus and a small inconspicuous nucleolus.
Malignant nodular hidradenoma MNH also known as hidradenocarcinoma is very rare adnexal tumor with exceedingly low incidence of 0. Cytosmears showed nodulra cohesive groups of uniform oval to polygonal cells with cytoplasmic clearing in some. None, Conflict of Interest: Cytomorphological features of nodular hidradenoma highlighting eccrine differentiation: The solid portion of tumor displayed polygonal to round tumor cells with eosinophilic cytoplasm and coarse nuclear chromatin.
This was an observation by Verma et al.

This study will highlight the importance of appropriate wide excision of primary adnexal tumors and thereby preventing metastatic presentations in future. Sebaceous differentiation is also common. Micrograph showing an acrospiroma. hiddadenoma
Apocrine hidradenomas are more common, contrary to earlier belief that favored an eccrine origin. Cytology, histopathology, hidradenocarcinoma, inguinal mass, metastasis.
