Waistband Mycosis Fungoides: A New Clinical Variant of Early-Stage Disease.

Case 1: A 17-year-old white man was referred for evaluation of biopsy-proven patch-stage mycosis fungoides (MF) that had first appeared 5 years previously. Asymptomatic "bruises" had appeared under his football padding in a waistband distribution, and these lesions improved during each offseason but never fully resolved. His exposure history was only positive for swimming pool water and his athletic pads.

A Case of Cycloserine-Induced Lichenoid Drug Eruption Supported by the Lymphocyte Transformation Test.

Lichenoid drug eruption (LDE) is a rare form of delayed-type drug eruption. Among anti-tuberculosis (Tb) agents, cycloserine (CS) has been reported as a rare cause of LDE. Positive results on the lymphocyte transformation test (LTT) have not been reported in patients with LDE.

Lymphomatoid papulosis: Treatment response and associated lymphomas in a study of 180 patients.

Background: Lymphomatoid papulosis (LyP) is a CD30(+) lymphoproliferative disorder, with a self-regressing clinical course and malignant histopathology.

Objective: The aim of this study was to evaluate characteristics, risk factors, associated malignancies, long-term outcome, and treatment of LyP in a large cohort representing the experience of the MD Anderson Cancer Center.

Methods: Patient charts and clinical and histopathologic data of 180 patients with LyP were retrospectively assessed.

A case of indeterminate dendritic cell tumor presenting with leonine facies.

Background: Indeterminate dendritic cell tumor is an extremely rare neoplastic proliferation of dendritic cells that share immunophenotypic features of Langerhans cells and macrophages but lack Birbeck granules and Langerin expression.

Methods: We report a 55-year-old female presenting with a leonine facies and generalized multiple confluent papules, nodules and plaques on neck, upper trunk, arms and thighs. Laboratory evaluations were performed including skin biopsies, peripheral blood flow cytometry and positron emission tomography-computed tomography.

Stevens-johnson syndrome induced by vandetanib.

Vandetanib is a once-daily oral anticancer drug that selectively inhibits key signaling pathways in cancer by targeting vascular endothelial growth factor receptors, epidermal growth factor receptors tyrosine kinase, and rearranged during transfection-dependent tumor cell proliferation and survival. The most frequently reported adverse events attributed to vandetanib include diarrhea, elevated aminotransferase, asymptomatic corrected QT interval prolongation, and hypertension. Though a number of randomized, doubleblind studies, including cutaneous adverse events attributed to vandetanib, have been reported along with these general symptoms, no case of Stevens-Johnson syndrome (SJS) has been reported.

Fluconazole induced fixed drug eruption.

We report on a rare case of fluconazole induced fixed drug eruption in a 62-year old female patient. She was referred to our department for multiple erythematous itchy maculopatches on the face, neck, both upper arms, and trunk area, which had occurred over the previous 6 months. Her attending physician prescribed fluconazole for treatment of onychomycosis.

Cutaneous malignant melanoma associated with papillary thyroid cancer.

As the survival from cutaneous malignant melanoma and its clinical concerns have been steadily increasing, the possibility has been raised of an increased risk of second primary cancers in the patients with malignant melanoma. Especially, recent studies have identified an association between cutaneous malignant melanoma and thyroid carcinoma. We here report on a case of cutaneous malignant melanoma that developed in a 61-year-old female patient who had hypothyroidism caused by papillary thyroid carcinoma.

Treatment of oral lichen sclerosus with 1% pimecrolimus cream.

Lichen sclerosus is a chronic inflammatory mucocutaneous disorder predominately affecting prepubertal girls and postmenopausal women. Isolated lichen sclerosus affecting the oral mucosa is exceedingly rare, and only 13 patients with biopsy-proved isolated oral disease have been reported in the literature. We report on a 7-year-old Korean girl with a well-demarcated 1.

Malignant Acanthosis Nigricans Associated with Ovarian Cancer.

Malignant acanthosis nigricans is a cutaneous eruption characterized by symmetric hyperpigmented hyperkeratosis, dermal papillomatosis, and mucosal involvement associated with internal malignancies. Tripe palms refers to a characteristic velvety thickening of the palms, with exaggeration of normal skin markings. We present the second case of ovarian cancer in association with two coexisting paraneoplastic dermatoses occurring in a 57-year-old Korean female.

P27 and mib1 expression in actinic keratosis, Bowen disease, and squamous cell carcinoma.

The histologic boundary between actinic keratosis, Bowen disease, and invasive squamous cell carcinoma is not clear in many cases. We determined nuclear expression of p27 (a protein associated with cellular quiescence) and Ki-67 (a marker of proliferation) immunohistochemically in actinic keratosis, Bowen disease, and squamous cell carcinoma to see if differential patterns of expression for p27 exist and how these might correlate with Ki-67 expression. We determined a labeling index for p27-stained nuclei and assessed the pattern of Ki-67 expression.

A case suggesting lymphocytic vasculitis as a presenting sign of early undifferentiated connective tissue disease.

A previously healthy 14-year-old Korean male presented with striking hemorrhagic acral livedo associated with anti-ribonucleoprotein antibodies. His skin biopsy revealed a striking lymphocytic vascular reaction with mild superficial perivascular lymphocytic infiltrates, perivascular extravasation of red blood cells, and leukocytoclastic debris. Lymphocytic vasculitis (LV) is defined in different ways by different authors.

Gianotti-Crosti syndrome following Japanese encephalitis vaccination.

We report a three-year-old Korean boy who presented with itching symmetrical erythematous macules and papules on his face, trunk, and extremities for 1 week. Lymphadenopathies were detected on physical examination. He was vaccinated against Japanese B Encephalitis (JE) 1 day before developing skin rashes.
