A nationwide study of acne treatment patterns in Korea: analysis of patient preconceived notions and dermatologist suggestion for treatment.

Patients often have preconceived notions about acne treatments before visiting dermatologists. The aim of this study was to explore the association between patients' beliefs regarding acne and physicians' suggestion for treatment modality in dermatology clinics. A cross-sectional, nationwide multicentre study was conducted.

Sphingosine may have cytotoxic effects via apoptosis on the growth of keloid fibroblasts.

Keloids are often resistant to treatment, causing much suffering to the patient. Our previous work found that ceramide (Cer) inhibits growth of fibroblasts via apoptosis. However, when compared to normal fibroblasts (NFs), which are quiescent, keloid fibroblasts (KFs) rapidly proliferate and are reported to be resistant to apoptosis via Cer.

Microvenular hemangioma in a boy with acute myelogenous leukemia.

Microvenular hemangioma (MVH) is a rare, benign, acquired vascular tumor. We report a case that shows the characteristic histopathologic features of this disorder in a boy with acute myelogenous leukemia (AML), suggesting an association with systemic immunosuppression.

A case of congenital mucinous nevus: a connective tissue nevus of the proteoglycan type.

Mucinous nevus is a very rare entity and can be classified as both a cutaneous mucinosis (CM) and a connective tissue nevus (CTN). We describe the clinicopathologic features of an unusual case of mucinous nevus in a 14-year-old Korean boy who presented with zosteriform plaques of congenital onset.

Generalized perforating granuloma annulare in an infant.

Generalized perforating granuloma annulare presents with flesh- to red-colored, 1-5 mm papules with a central umbilicated crust or scale that usually involves the extremities, face, neck, and trunk. Perforating granulomas are demonstrated on histopathology. Our patient is a 68-day-old girl with generalized perforating granuloma annulare.

Relative frequency of the different types of cutaneous T cell and natural killer cell lymphomas in Korea based on the proposed WHO classification and the EORTC classification.

A case of infantile acne due to pityrosporum.

We report a case of infantile acne. The lesion on the forehead resembled infantile acne clinically, but histologically it contained yeasts of Pityrosporum. The lesion was treated with topical ketoconazole cream and improved.

Scabies incognito presenting as urticaria pigmentosa in an infant.

Misdiagnosis is frequent in scabies of infants and children because of a low index of suspicion, secondary eczematous changes, and inappropriate therapy. Topical or systemic corticosteroids may modify the clinical presentation of scabies and that situation is referred to as scabies incognito. We describe a 10-month-old infant with scabies incognito mimicking urticaria pigmentosa.

Tinea capitis due to Trichophyton rubrum in a neonate.

Tinea capitis is a common infection of school-aged children, but there have been only a few reports of tinea capitis in newborns. Furthermore, Trichophyton rubrum as a causative organism of tinea capitis is documented very rarely. We report herein a neonate in whom T.

Intradermal nodular fasciitis of the face.

Nodular fasciitis represents reactive myofibroblastic proliferative lesions in the subcutaneous tissue, skeletal muscles, and fascia. Uncommon clinical and pathological variants of nodular fasciitis, such as intravascular, cranial, ossifying, and proliferative fasciitis, have been described. Six cases documenting a dermal location of nodular fasciitis have been reported in the English literature.

Comparison of primary and secondary cutaneous CD56+ NK/T cell lymphomas.

CD56+ NK/T cell lymphoma (NKTL) frequently involves skin and subcutaneous tissue. The characteristics of primary cutaneous nasal-type CD56+ NKTLs and secondary cutaneous involvement of nasal CD56+ NKTLs have not been clearly separated. This retrospective study analyzed 15 cases of NKTL (10 primary CD56+ NKTLs and 5 secondary CD56+ NKTLs) for their clinicopathologic and immunophenotypic characteristics using CD3, CD4, CD20, CD45RO, CD56, TIA-1, CD30, and Ki-67 antigens.
