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.

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.

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.

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.

Cutaneous horn is the clinical description of a hyperproliferation of compact keratin in response to a wide array of underlying benign and malignant pathologic changes. We report here on a case of cutaneous horn that originated from keratoacanthoma in a 76-year-old woman. Grossly, a 2.5x0.7 cm sized yellow-white colored scaly fungating mass from an erythematous nodule was observed on the right temporal area. Histopathologically, it was reported as keratoacanthoma with cutaneous horn. The lesion was totally excised after the diagnosis.

Trichilemmal cyst is a benign tumor that originates from the external root sheath. It usually occurs on the scalp, but rarely on the face, neck and trunk. A 41-year-old man presented with a skin-colored non-tender subcutaneous nodule on his abdomen. The histopathologic findings of the lesion showed a well demarcated cystic mass with trichilemmal keratinization in the dermis. It was diagnosed as a trichilemmal cyst and then it was totally excised. We report here on a case of trichilemmal cyst on the abdomen, which is known to be an unusual site for this type of lesion.

PURPOSE: The purpose of this study was to compare clinical effect of the Langer & Langer technique , the modified Langer & Langer technique and Bruno technique. MATERIAL AND METHODS: 30 patients who have gingiva recession(Miller class I or class II) were carried root coverage. Langer & Langer technique(14 patients/32 tooth), modified Langer & Langer technique(5 patients/10 tooth) and Bruno technique(11 patients/18 tooth) was carried. At baseline and average 3 months after operation, it was estimated clinical index(Pocket depth, gingiva recession, clinical attachment level, keratinized gingiva, scar tissue, root coverage rate) by Williams style probe. RESULT: Root coverage rate is indicated Langer & Langer technique(85%), Modified Langer & Langer technique(86%) and Bruno technique(90%). CONCLUSION: All three of the procedures were effective in gingival recession and improved clinical parameters.
