Clinically, it appeared as a blackish plaque measuring 4 cm in diameter, with a hyperkeratotic surface and an area with brownish pigment that could be seen in the anterosuperior portion. Dermoscopy showed radiate striae and pseudopods on the periphery of this region (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>), structures found in melanocytic lesions and commonly associated with malignant melanoma. The lesion had been ongoing for ten years, was painless, and there were no other associated symptoms; nor a history of previous cutaneous malignancy in the region.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0015" class="elsevierStylePara elsevierViewall">Diagnostic hypotheses included malignant melanoma, pigmented basal cell carcinoma, and seborrheic keratosis. An incisional spindle biopsy was chosen due to the size of the lesion. Histopathology revealed the proliferation of basaloid cells forming thin anastomosing cords, connected to the hyperorthokeratotic epidermis, containing lumens and areas of atypia, with sparse pigmented dendritic melanocytes among the atypical basaloid cells (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). The melanocytes were easily visible and did not proliferate continously or in nests indicating an associated nevus or melanoma. Immunohistochemistry with Melan-A (A103, mouse monoclonal, Merck KGaATM) revealed sparse dendritic melanocytes among the atypical epithelial cells of the eccrine syringofibroadenocarcinoma (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>). The basaloid cells were immunostained with EMA, epithelial membrane antigen (E29, mouse monoclonal, Merck KGaA™) and with Ki-67 (SP6, rabbit monoclonal, Merck KGaA™); there was a high proliferative index in groups of atypical basaloid cells within the epidermis. It was also observed that the epithelial cells labeled with EMA were the same ones that exhibited a high proliferative index with Ki-67 (<a class="elsevierStyleCrossRef" href="#fig0020">Fig. 4</a>A‒C). Carcinoembryonic antigen, CEA (CEA31, mouse monoclonal, Merck KGaA™) positivity was observed only around the lumens present in the basaloid cell cords (<a class="elsevierStyleCrossRef" href="#fig0020">Fig. 4</a>D). The diagnosis of pigmented eccrine syringofibroadenocarcinoma was thus made. The absence of thick cords corroborated the diagnostic exclusion of eccrine porocarcinoma, and the presence of ductal differentiation contributed to the diagnostic exclusion of squamous cell carcinoma.</p><elsevierMultimedia ident="fig0010"></elsevierMultimedia><elsevierMultimedia ident="fig0015"></elsevierMultimedia><elsevierMultimedia ident="fig0020"></elsevierMultimedia><p id="par0020" class="elsevierStylePara elsevierViewall">The lesion was submitted to surgical excision with a 1-cm margin.

Surgical excision with complete removal of the lesion is currently the treatment of choice. The histochemical and immunohistochemical analyses of the excised lesion showed in its entirety the same findings found in the incisional biopsy.</p><p id="par0025" class="elsevierStylePara elsevierViewall">ESFA is most commonly found as single, slow-growing plaques or nodules on the extremities of elderly patients. On histopathology, it is represented by thin cords of epithelial cells that anastomose, extending from the epidermis towards the dermis circumscribed by a fibrous stroma, with luminal structures within the epithelial cords. Ductal cells, as well as the cord areas, may show positive expression for CEA. EMA is found diffusely in ductal cells. Its true origin is controversial, but it is believed to be derived from the acrosyringium and eccrine dermal ducts.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a></p><p id="par0030" class="elsevierStylePara elsevierViewall">In 1997, Starink proposed the ESFA classification into four subtypes: (1) Solitary - non-hereditary, with variable presentation, more prevalent in the middle-aged and the elderly; (2) Associated with Schöpf syndrome - hereditary, with erythematous papules on the palms and soles - Schopf-Schulz-Passarge syndrome (SSPS) is a rare type of ectodermal dysplasia with autosomal recessive inheritance. It is characterized by palmoplantar keratoderma, hypodontia, hypotrichosis, nail dystrophy and multiple periocular and eyelid apocrine hydrocystomas; (3) Multiple lesions not associated with SSPS; (4) Non-familial unilateral linear lesions.
