Obsessive-compulsive disorder in dermatology.

Obsessive-compulsive disorder (OCD) is a very common disorder affecting 2% to 3% of the general population. Up to 25% of patients presenting to physicians with skin disease suffer from OCD. Only 20% of all patients with OCD are receiving treatment.

Two cases of acute generalized exanthematous pustulosis related to oral terbinafine and an analysis of the clinical reaction pattern.

Acute generalized exanthematous pustulosis (AGEP) is a clinical reaction pattern characterized by the rapid appearance of widespread sterile, nonfollicular pustules arising within edematous erythematous skin. This aseptic pustular eruption is commonly accompanied by leukocytosis and fever and usually follows recent administration of oral or parenteral drugs. We report two cases of terbinafine-induced AGEP in male patients.

Granulomatous slack skin without evidence of a clonal T-cell proliferation.

Granulomatous slack skin is a rare cutaneous disorder with less than 50 cases presented in the English-language literature. The disease is characterized by circumscribed erythematous lax skin accentuated most commonly in the axillary and inguinal areas. A strong association with a preceding or evolving diagnosis of mycosis fungoides or Hodgkin's disease has been reported.

Cutaneous Mycobacterium chelonae in a liver transplant patient.

A 51-year-old woman with an orthotopic liver transplant on tacrolimus (SKF 506) and prednisone presented with an erythematous ulcerated nodule on the knee. No preceding trauma was noted. A skin biopsy specimen demonstrated beaded gram-positive, acid-fast rods and the skin culture grew Mycobacterium chelonae (formerly M chelonae subsp chelonae ).

Neuroendocrine differentiation of a metastatic basal cell carcinoma in a patient with basal cell nevus syndrome.

A 48 year-old white male with basal cell nevus syndrome presented with a metastatic basal cell carcinoma with neuroendocrine features. The tumor manifested aggressive behavior, having deep local invasion and metastases to para-aortic lymph nodes and bone. Neuroendocrine differentiation has rarely been associated with basal cell carcinoma.

Leukemia cutis with prominent giant cell reaction.

We present a case of leukemia cutis associated with a prominent giant cell component. This lesion was initially diagnosed as chronic granulomatous inflammation 1 year before the definitive diagnosis of leukemia cutis was made. Skin biopsy specimens showed numerous Langhans-type giant cells occurring singly and as poorly formed granulomas.

Obsessive-compulsive disorder.

The prevalence of OCD in a dermatologic practice may be much higher than in the general population. OCDs can be debilitating in one's interpersonal, social, and occupational functioning. The obsessions and compulsions typically begin fairly early in life and may consume prolonged lengths of the patient's time to complete daily rituals of washing, checking, touching, arranging, hoarding, or ruminating.

Pharmacologic treatment of severe skin-picking behaviors in Prader-Willi syndrome. Two case reports.

Background: Prader-Willi syndrome (PWS) is characterized by hypotonia at birth, hypogonadism, early childhood obesity, and mental deficiency. Other behavioral symptoms that become prominent during adolescence and adulthood include temper outbursts, stealing and hoarding food, and skin picking. The self-excoriating skin picking behavior observed in individuals with PWS is quite common and can lead to persistent sores and infections, even requiring hospitalization.

Intraoral vesicles occurring after alginate impressions.

In 47 of 227 dental students intraoral vesicles developed after multiple alginate impressions. The lesions were generally solitary and clear, and appeared within 24 to 48 hours after the impression. They were most frequently located inside the vermilion border of the lips and resolved spontaneously in 2 to 5 days.

Hereditary acrodermatitis enteropathica in an adult.

The condition of a 33-year-old woman who had a history of blisters following trauma on the hands, knees, and feet since 1 year of age previously had been diagnosed as epidermolysis bullosa. She also had psoriasiform plaques, a pustular crusted periorificial eruption, paronychia, alopecia, and photophobia. She had had minimal history of diarrhea.
