Disseminated superficial porokeratosis (DSP) is a keratinization disorder characterized by multiple small lesions with a slightly elevated, sharply defined ridge over the whole body. Inflammatory DSP has common clinical features, which involve a several-year history of asymptomatic DSP and the sudden appearance of intensively pruritic erythematous papules over the entire body. These lesions subside within several months, leaving a brownish atrophic lesion. We report on a 64-year-old man who displayed an atypical clinical feature of inflammatory DSP.

Darier's disease is a genetic disorder of keratinization with autosomal dominant inheritance. Its appearance is usually in the form of greasy, crusted, keratotic yellow-brown papules and plaques found particularly on seborrheic areas of the body. However, there are some clinical variants showing atypical skin lesions. Here we report an unusual case of Darier's disease, which mainly showed prominent comedonal papules over the face.

Granular parakeratosis is a recently recognized disorder of keratinization that is usually confined to intertriginous areas. The histopathologic features are distinctive and diagnostic. Rarely, histopathologic variants such as follicular granular parakeratosis and granular parakeratosis of eccrine ostia have been described. In this report, we describe a rare case of granular parakeratosis mostly confined to eccrine ostia.

6.Intraosseous Epidermal Inclusion Cyst in the Distal Phalanx of Thumb with Cortical Destruction: A Case Report and Review of Literature.

Intraosseous epidermal inclusion cyst is a rare benign, cystic lesion. It is thought to result from traumatic implantation of epidermal elements into bone. Radiologic findings of intraosseous epidermal inclusion cysts are well-defined, lytic lesions. It is difficult to diagnose intraosseous epidermal inclusion cyst without pathologic diagnosis. We experienced a 43-year-old man with a history of trauma followed by painless expansion of his left thumb. Radiographs demonstrated a severe expansile, ill-defined lytic lesion with cortical destruction in the distal phalanx of left thumb, mimicking neoplastic bone lesion or infectious lesion. An intraosseous epidermal inclusion cyst was confirmed by pathologic diagnosis, which was lined by stratified squamous epithelium, containing keratinized cellular debris.

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare disorder of keratinization, involving acrosyringium. Most cases were congenital, and showed linear distribution of multiple hyperkeratotic comedo-like papules and plaques located on acral extremities. Adult-onset cases were extremely rare in the English literatures and there have not been any reported cases in the Korean literatures. Moreover, there has been no report describing the dermoscopic features of PEODDN so far. So, we here report a rare case of adult-onset PEODDN with its dermoscopic finding and review of the relevant literatures.

Clear cell hidradenoma is a relatively infrequent benign tumor that shows differentiation from or toward the structure of the eccrine sweat gland. We report four cases of clear cell hidradenoma which consists mainly of typical clear cells with small numbers of polyhedral cells. Clinically these tumors represented solitary erythematous firm nodular or cystic mass. In immunohistochemical study of one case, polyhedral cells rather than clear cells reacted positively for carcinoembryonic antigen and cytokeratin. We also review the previous reports of clear cell hidradenoma in Korean dermatologic literature.

10.Secondary Milia Occurring after Bullous Cellulitis.

Milia are small, white to yellow, benign, superficial keratinous cysts. They are divided into primary or secondary cysts. Secondary milia are associated with disease, medication, and trauma. We report a case of a 45 year-old woman with grouped yellowish papules and brownish patches on her left ankle after bullous cellulitis. This case shows that bullous cellulitis may be one of the causes of secondary milia.
