Eccrine spiradenoma on the anterior forearm in a pediatric patient: A rare case report

Abstract

Key Clinical MessageSpiradenoma is a rare benign adnexal tumor arising from eccrine sweat glands. It presents as a painful bluish nodular lesion which occurs rarely over the arms. This case report adds to a case where a recurrent spiradenoma occurred over the arm. The majority of reported cases involve young adults, making our pediatric case particularly unusual. Early diagnosis through excisional biopsy is crucial for optimal management and prevention of recurrence or malignant transformation. Eccrine spiradenoma is an uncommon tumor that should be kept in mind in case of a patient with a painful nodule. More genetic studies are needed for the best understanding of this rare tumor entity.

A rare case of spiradenoma or a common sebaceous cyst? - A case study

“…It is possible for spiradenoma to appear along with cylindroma, trichoepitheloma and it increases occurrence of Brooke-Spiegler syndrome [8]. When suspecting a spiradenoma diagnosis, it is important to differentiate it with the following: anaplastic or basal cell carcinoma, adenocarcinoma or sebaceous cyst [9]. This tumor transforms into malignant form extremely rarely.…”
