pilomatrixoma/edema

The follicular hybrid is composed of more than two components of pilosebaceous unit. There are several studies of hybrid cyst, combination of trichilemmal and epidermoid cyst was the most frequently reported. In this paper, we reported one case of hybrid cyst composed of bullous pilomatricoma and

Perforating pilomatricoma (PP) is a rare clinical variant of pilomatricoma presenting as a crusted or ulcerated nodule. Previous reports have suggested that the tumor cells perforate the epidermis through a process of transepithelial elimination. Here, we report six cases of PP and examine the

Pilomatrixoma presents clinical variants, ulcerated and tumorous, angioid and one very special type characterized because the skin covering the tumor is very thin (anetodermic), pink and folded, simulating an involuting blister. The authors that observed six cases of this variant, considered that

Pilomatricoma is an uncommon hamartomatous tumor of the hair matrix. Bullous and anetodermic changes over pilomatricoma are rare. We report an 18-year-old male with an asymptomatic nodule with overlying cystic changes on the left arm of 6-month duration with clinical and histological features of

BACKGROUND Pilomatricoma is a common benign adnexal tumor differentiating toward elements of the hair matrix and shaft. It typically presents as a solitary, deep, dermal nodule. We describe a case of a pilomatricoma with the unusual feature of a thick-walled dermal bulla overlying the

Five pilomatrixomas with anetodermic cutaneous changes are presented. Four large tumors revealed soft, atrophic, pink translucent skin covering a firm subcutaneous mass, and their appearance was similar to that of a keloid or hypertrophic scar. One small tumor revealed soft, slightly atrophic,

BACKGROUND The casual observation of a peritumoral edema with collagenolysis in a case of eccrine spiradenoma led us to search for similar lesions in a retrospective series of 50 spiradenomas. METHODS Among 50 cases of eccrine spiradenomas, 36 excised with the overlying epidermis and the surrounding
