El poroma ecrino (PE) corresponde a una neoplasia anexial benigna originada de la porción intraepidérmica del conducto de las glándulas sudoríparas. Habitualmente se describe como nódulos eritematosos o color piel ubicados en región palmoplantar, pero sus características clínicas son muy variables. Se decriben los hallazgos clínicos y dermatoscópicos de una serie de casos de pacientes con PE. La dermatoscopia puede facilitar significativamente el diagnóstico clínico de la mayoría de los tumores de la piel, sin embargo el PE se caracteriza por un alto grado de variabilidad a la dermatoscopía. Habitualmente se describe un patrón vascula polimorfo con vasos glomerulares, en horquilla, y lineales irregulares con terminaciones semicirculares rodeados de un halo blanco a rosa en forma de caliz o flor de cerezo asociado a áreas rosadas blanquecinas sin estructuras similares a lo observado en melanoma amelanótico, carcinoma espinocelular entre otros tumores benignos y malignos. El PE puede exhibir características clínicas y dermatoscópicas polimórficas que pueden hacer difícil el diagnóstico y su diferenciación de otras neoplasias cutáneas.
Eccrine poroma (PE) is a benign adnexal neoplasm of the intraepidermal portion of the sweat gland duct. PE typically present as erythematous or flesh-colored nodules on the palms and soles, but the clinical features of PE are highly variable. Dermatoscopic and clinical findings of patients with EP are described. Dermoscopy may significantly improves the clinical diagnosis of most skin tumours, but PE is characterised by a high degree of dermoscopic variability. The main dermoscopic features described are polymorphous vascular pattern, whiteto- pink halo surrounding the vessels, pink-white structureless areas, vascular structures of glomerular, hairpin vessels, and linear irregular vessels, mimicking amelanotic melanoma, keratinising tumours and several benign and malignant tumors. Eccrine poroma may exhibit polymorphic clinical and dermoscopic features making it difficult to diagnosis and differentiate from other skin cancers.

Background: We report a 35-year-old female patient with a one year history of a pustular and painful erythematous dermatitis, located in great folds, pubis and abdomen. She was evaluated in primary health care, receiving antifungal treatment, antimicrobials, topical and systemic non-steroidal anti-inflammatory drugs, with no response. A skin biopsy was compatible with subcorneal pustular dermatosis. She was initially treated with prednisone (0.8 mg/kg), observing a partial response. Therefore clotrimoxazole was initiated, obtaining an excellent response after 30 days of treatment.
