Seborrheic Keratosis of Areola Treated with Topical Calcipotriol Ointment / 대한피부과학회지

A synthetic analogue of calcitriol (1,25-dihydroxymitamin D3), has shown immunomodulatory effects as well as induction of cell differentiation and inhibition of cell proliferation. This agent has been widely used for psoriasis. We report a case of seborrheic keratosis of the left areola in a 33-year-old female who was treated with calcipotriol ointment. Because of the lesion's location and shape, it was difficult to try ablative methods. However, complete disappearance of the lesion was observed after 6 weeks of topical calcipotriol application. This case suggests that the calcipotriol ointment is effective in the treatment of seborrheic keratosis.

Tinea Incognito Caused by Application of 0.03% Tacrolimus (Protopic(R)) Ointment in Atopic Dermatitis Patient / 대한의진균학회지

We report a case of tinea incognito in a 29-year-old man after applying the 0.03% tacrolimus ointment. He was known atopic dermatitis patient and has been treated with intermittent application of tacrolimus. For his facial pruritus 0.03% tacrolimus ointment was prescribed, and after one week he developed annularly grouped erythematous plaques and patches around the ointment-applied area. The KOH smear revealed multiple fungal hyphae. Dermatologists should be aware of the possibility of topical tacrolimus to be the causative agent for tinea incognito.

Febrile Ulceronecotic Pityriasis Lichenoides et Varioliformis Acuta Successfully Treated with Oral Cyclosporin / 대한피부과학회지

Febrile ulceronecrotic pityriasis lichenoides et varioliformis acuta (PLEVA), or febrile ulcerative Mucha-Haberman disease (FUMHD) is very rare, but potentially lethal variants of PLEVA. This subtype is characterized by rapidly progressive ulceronecrotic lesions and systemic manifestations, such as high fever, gastrointestinal, neurological, cardiologic and pulmonary involvement, and rheumatologic manifestations. Several treatments with variable response have been challenged, such as systemic steroid, antibiotics, methotrexate, dapsone, cyclosporine and ultraviolet therapy. But there is no standard therapy for FUMHD to date. We report a 59-year-old woman with FUMHD, who recurred after discontinuation of systemic steroid, but successfully treated with oral cyclosporine.

Ulcerative Infantile Hemangioma Treated with Topical Timolol / 대한피부과학회지

Therapeutic options for infantile hemangioma are limited. The nonselective beta-adrenergic receptor antagonist propranolol is an effective therapy for infantile hemangiomas. However, systemic propranolol carries a risk of serious side effects, including bradycardia, hypoglycemia, arrhythmias, hypotension and bronchospasm. Recently, treatment of infantile hemangioma with topical timolol (nonselective beta-blocker similar to propranolol) has been reported. We treated successfully the perineal ulcerative hemangioma with topical timolol. We believe that timolol is a safe and effective topical agent and should be strongly considered as one of good therapeutic options for hemagnioma.

Multiple Congenital Melanocytic Nevi Associated with Developmental Delay / 대한피부과학회지

Multiple congenital melanocytic nevi (MCMN), defined as the distribution of more than three small- or medium- sized congenital melanocytic nevi (CMN) on the body without a giant CMN, is a rare disease comprising about 4% of patients with CMN. Because MCMN accompanies neurodevelopmental delay, including seizures in 25% of patients as well as the risk of malignant melanoma, it must be carefully followed-up. We report a case of MCMN with developmental delay in a 19-month-old Korean boy. He had a history of febrile seizure when he was 18 months old. He showed a speech delay after the 1-year-follow up, even though there was no evidence of neurocutaneous melanosis (NCM) on brain magnetic resonance imaging (MRI) at the first visit. As MRI has a low sensitivity for detecting NCM in patients with MCMN older than 4-months, close neurodevelopmental assessments should be considered to provide a chance for early rehabilitation.

Squamous Cell Carcinoma Arising in Pre-existing Seborrheic Keratosis / 대한피부과학회지

Seborrheic keratosis is one of the most common benign epithelial tumors, especially in elderly patients. Squamous cell carcinoma is the second most common malignant tumor of the skin. Despite the fact that both tumors are common, malignant transformation of seborrheic keratosis rarely occurs. Herein we report a case of squamous cell carcinoma arising in a patient with pre-existing seborrheic keratosis.

A Case of Mycosis Fungoides Concurrent with Lymphomatoid Papulosis / 대한피부과학회지

Mycosis fungoides (MF) is the most frequent cutaneous T cell lymphoma (CTCL). Since the major tumor cell of MF is the helper T cell, positive markers are usually CD3, CD4 and CD45RO. Some MFs show CD30 positivity and the major differential diagnosis for MF with CD30 positivity includes transformed MF and MF concurrent with primary cutaneous anaplastic large cell lymphoma and lymphomatoid papulosis. As each disease shows a different prognosis, an exact diagnosis is crucial for proper treatment. We now report a case of 44-year-old male patient with mycosis fungoides which developed several papules on preexisting MF patches. On biopsy of the newly formed papules, CD 30 positive cells were observed and the histologic features were consistent with lymphomatoid papulosis. Both the lesions of lymphomatoid papulosis and MF responded well to narrow band ultraviolet B phototherapy.

Chemical Leukoderma Improved by Low-dose Steroid Pulse Therapy

Chemical leukoderma occurs due to the toxic effect of a specific chemical preceding allergic contact dermatitis. The mechanism is either destruction or inhibition of melanocytes by the offending substance. Clinicohistopathologically, no absolute criteria can differentiate chemical leukoderma from vitiligo. However, chemical leukoderma can be diagnosed clinically by a history of repeated exposure to a known or suspected depigmenting agent at the primary site. There is no agreed treatment guideline for chemical leukoderma. We report a healthy 51-year-old man who had multiple hypopigmented macules and patches on his face, neck, arms and legs after exposure to occupationally related chemicals. The lesions were recalcitrant to topical corticosteroids, but they showed much improvement after 3 cycles of systemic steroid pulse therapy. We suggest this therapy may be a good treatment option for chemical leukoderma.
