Hidradenoma with an atypical localization mimicking lipoma

Abstract

Sir, Nodular hidradenoma is a rare, benign adnexal tumor usually located in the head, neck, and extremities [1]. The difficulty of the diagnosis is due to the non-specificity of the clinical and histological presentation, often requiring a clinicopathological correlation [2]. Herein, we report a case of atypical abdominal hidradenoma mimicking lipoma. Our patient was a 51-year-old Moroccan female operated for bowel obstruction and fibroma presenting with a slowly growing, painless, subcutaneous abdominal nodule persistent for the last two years. The nodule had gradually increased in size in a context of apyrexia and general state preservation. A clinical examination was remarkable for a subcutaneous nodule (2.5 cm long axis) at the left iliac fossa, painless, indurated, and not fixed to the deep tissues, with slightly purplish skin (Fig. 1). The rest of the examination was featureless. In addition, dermoscopy was non-specific.

Diagnostic wandering of a case of giant pedicled lipoma of the left inguinal fold

“…The soft consistency and pedunculated appearance at first evoked molluscum pendulum, similarly to our daily practice, or inguinal hernia [2], yet the non-depressible aspect such as a hollowed out grape grain was not in favor. Differential diagnosis was also made with other soft tissue tumors such as angio-eccrine hamartoma [7] and hidradenoma [8]. Some authors opt for primary liposuction to reduce tumor volume, because the aesthetic result would be more satisfactory and post-operative morbidity would be decreased [3,6].…”
