“…Il s'observe chez l'adulte à partir de la trentaine et siège le plus souvent au niveau des membres inférieurs ou au niveau des extrémités en particularité les régions palmo-plantaires [5]. La tumeur apparaît sous la forme d'une lésion saillante, bien limitée, à surface érythémateuse et parfois un peu suintante, attirant l'attention à l'examen clinique [5,10]. Sur le plan histologique, la tumeur est faite de grandes travées de petites cellules rondes formant des nappes très homogènes connectées à l'épiderme et descendant dans le derme moyen et profond (Fig.…”

Introduction:The tumours of skin adnexal are rare and very often benign. Because of their large diversity they caused some diagnose and classification problems. They are tumours of ten mixed up with other skin tumours. The objective of this study was to study the histopathological and epidemiological profile of the benign skin adnexal tumours in Ouagadougou and to classify them according to the differenciation type in order to well know them and improve their treatment. Methodology: We conducted a retrospective study on the period of sixteen years going from 1 st January 1998 to 31 December 2013. This study interested all cases of benign skin adnexal tumours histologically confirmed (diagnosed) in the three pathology laboratories of the Ouagadougou town. Results: We collected sixty cases of skin adnexal tumours on the total of 763 cases of skin tumours representing 7.8%. The benign tumours represented 86 % of the adnexal tumour cases. These tumours were occurred in the relatively young age and were preferentially located on the head (cephalic) extremity. On the histological plan, the hair follicle tumours were more frequent (42.5%) followed by sweat gland tumours (30.5%) and sebaceous gland tumours (27%). Conclusion: The annex tumours are majoritary benign occurring often on the head extremity and dominated by the hair follicle tumours.

Poromas are uncommon benign neoplasms originating from the terminal ductal portion of the sweat glands, mainly characterized by skin-colored or pink pa pules or nodules, usually on the extremities. Due to their rarity, the pigmented form clinical hypothesis is hardly ever suggested and psychopathology is fundamental. We report a case of pigmented eccrine poroma in the right palmer area, a location considered atypical. We stress the importance of dermoscopy as a method for diagnosis of poromas, especially in the differential diagnosis with other pigmented nodular-popular lesions.

Eccrine poroma is a rare benign adnexal tumor of epithelial cells originating from the terminal ductal portion of the sweat glands that is typically located on palms and soles, although other cutaneous sites can be affected [1]. It is usually nonpigmented even if there is a pigmented variant that corresponds to 17% of cases and it is usually underdiagnosed, since it is mistakenly confused with other pigmented tumors [2,3]. Dermoscopy and reflectance confocal microscopy (RCM) may assist in the correct diagnosis of this tumor.Herein, we report one case of pigmented eccrine poroma (PEP) that simulated clinically a cutaneous melanoma or a basal cell carcinoma. Dermoscopy and RCM excluded the possibilities of those two diagnoses; the overall confocal findings were suggestive for a benign epithelial tumor. Histology was fundamental to diagnose this lesion as a pigmented eccrine poroma. Even if the diagnosis of eccrine poroma remains histopathological still, as in this case report, noninvasive tools such as dermoscopy and RCM examinations can be of help to rule out the diagnosis of melanoma. Larger studies on this rare pigmented variant of eccrine poroma could shed new light on the identification of specific diagnostic dermoscopic and confocal features.
