Wilson et al. reported that papular acne scars represent postacne scars and they are indistinguishable from those described as papular elastorrhexis. However, papular elastorrhexis differs from postacne scars in some aspects. First of all, papular elastorrhexis is nonfollicular oriented. In addition, acne lesions are not usually located on the arms, thighs and abdomen. These findings [...]
Papular elastorrhexis occurs predominantly in the 2nd decade as discrete whitish firm papules with the focal decrease and fragmentation of elastic fibers.
A 20-year-old Korean woman presented with several months, history of asymptomatic, multiple papules on the anterior chest, which had been gradually increasing in number. On physical examination, we observed multiple discrete nonfollicular 2 to 5 mm sized firm, slightly indurated, whitish papules that were scattered symmetrically on the anterior chest (Fig. 1). There was no [...]
INTRODUCTION Connective tissue nevi are dermal connective tissue hamartomas that are characterized by an imbalance in the relative amount and distribution of collagen, elastin or proteoglycan. If elastic fibers are exclusively involved, then elastic tissue nevus would be the appropriate term. Papular elastorrhexis is an uncommon disease that usually occurs in childhood or adolescence with [...]
The follicular hybrid cyst was first described by McGavran and Binnington in 1966 as a cystic tumor that was a combination of an epidermal cyst and a trichilemmal cyst. In the reports by Requena and Sanchez in 1991, the concept of a follicular hybrid cyst was extended to a cystic lesion that included more than [...]
A 28-year-old Korean woman presented with an 8-month history of a slowly-enlarging and hardening subcutaneous tumor on the lateral side of her left thigh. She initially recognized the lesion as a small bean-sized nodule but it slowly enlarged and hardened. There were no signs or symptoms of Gardner’s syndrome. Physical examination revealed a 1.8 x [...]
INTRODUCTION An epidermal cyst is quite a common cystic disease of skin, which originates from the follicular infundibulm and contains stratified squamous epithelium with lamellar keratinized material. Pilomatricoma, a tumor with differentiation toward hair matrix cells, histologically shows basophilic cells and shadow cells with non-lamellar homogenous keratinized material. Rarely, pilomatricoma-like changes with sharply-bordered shadow cells [...]
