ABSTRACT
The incidence of skin disease secondary to infestation with the human bedbug, Cimex lectularius, has increased dramatically in the United States and in the United Kingdom. We describe a child with a recurrent pruritic eruption of urticarial, erythematous papules on the face, neck, and extremities. The etiology of her cutaneous lesions was discovered to be a bedbug infestation in the home. The epidemiology, entomology, presentation, and treatment of bedbugs and their bites are discussed.

BACKGROUND: Familial eccrine spiradenoma is a rare autosomal dominant condition that is characterized by slow-growing, benign adnexal tumors. OBJECTIVE: We investigated a case of familial eccrine spiradenoma displaying an autosomal dominant inheritance pattern. To our knowledge, only two previously reported cases of familial eccrine spiradenoma exist in the literature. METHODS: A case report and review of the literature are given. RESULTS: We report a case of familial eccrine spiradenoma in a mother and daughter and present successful treatment using surgical extirpation and CO2 laser ablation. CONCLUSION: Familial eccrine spiradenoma is a benign autosomal dominantly inherited condition that is characterized by tender, slow-growing, adnexal tumors of the head and neck. Surgical tumor extirpation and CO2 laser ablation offer both an effective symptomatic and cosmetically elegant treatment option.

The classification of inflammatory disorders of the subcutaneous tissue has mystified dermatologists for decades. Overlapping clinical and histologic features, and a lack of specific treatments have added to the confusion. This article initially classifies the various panniculititides by their primary histopathologic pattern: (1) septal panniculitis without vasculitis, (2) septal panniculitis with vasculitis, (3) lobular panniculitis without vasculitis, and (4) lobular panniculitis with vasculitis. Subsequently, we describe the key clinical findings in the most important forms of panniculitis. We begin with the most common form of panniculitis, erythema nodosum. Indeed, in many patients suspected of having panniculitis, a worthwhile question to consider initially might be, "Is this, or is this not, erythema nodosum?" before engaging in an elaborate (and expensive) exercise in differential diagnosis.
