Pruritic eruption with reticular pigmentation: Confluent and reticulate papillomatosis

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2007
Gursoy Dogan
SUMMARY A 28-year-old man presented with a 2-year history of a pruritic eruption on his neck, chest, back, axillae, and antecubital and pubic areas. The patient had been previously treated with topical and systemic antifungal therapy for a long time, but showed no response. Examination revealed the typical clinical and histological features of confluent and reticulate papillomatosis. The patient responded well to oral doxycycline. [source]

Annular atrophic lichen planus

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 5 2007
Rosa María Ponce-Olivera MD
A 30-year-old woman presented with a 1-year history of a pruritic eruption on the extremities, characterized by several annular plaques. The patient had been treated unsuccessfully with medium-potency topical steroids. The lesions had an erythematous papular border with an atrophic center (width, 1,4 cm) (Fig. 1). No oral, genital, or nail lesions were observed. Figure 1. Annular lesion with an infiltrated border and atrophic center A skin biopsy from one of the plaques was performed. Histopathologic examination of the raised border showed hyperkeratosis of the stratum corneum, focal thickening of the granular layer, basal liquefaction degeneration of the epidermis, and a band-like subepidermal infiltration with numerous Civatte bodies. In the center of the lesion, the epidermis became thinner (Fig. 2). Elastic fibers were reduced or absent in the papillary dermis. Figure 2. (a) Biopsy of the border of a plaque with the typical changes of lichen planus (hematoxylin and eosin, ×10), with flattened epidermis in the center of the plaque; (b) medium power of the border of the plaque with details of the changes of lichen planus (hematoxylin and eosin, ×40) The patient was treated with high-potency topical steroids for 2 months with clinical improvement.

A unique variant of Darier's disease

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 4 2001
Christopher M. Peterson MD
A 45-year-old black woman presented with a chief complaint of an increasing number of ,,light spots'' on her face, upper trunk, and legs. She had a 4-year history of a pruritic eruption on the dorsum of her hands. The eruption was particularly pruritic in the summer months. Other family members, including her sister and her daughters, reportedly had a similar dermatologic problem. The patient had been previously evaluated and biopsied by another dermatologist. The earlier biopsy was nondiagnostic, however, and she presented for further evaluation of this problem. On physical examination, the patient had hypopigmented macules along her jawline (Fig. 1), lateral neck, and upper chest. She had similar hypopigmented macules on her thighs. She had hyperkeratosis of the palmoplantar surface of her hands and feet. The dorsum of her hands had numerous coalescing, shiny, flat-topped, hypopigmented papules (Fig. 2), and several of her fingernails had distal, V-shaped notching. Figure 1. Hypopigmented macules on the cheek and along the jawline Figure 2. Coalescing, hypopigmented papules on the dorsal aspect of the fingers and hand, with distal notching of the fingernails A punch biopsy from a papule on the dorsum of her hand was obtained. The epidermis had corps ronds present with focal areas of acantholysis above the basal layer (Fig. 3). The dermis had sparse, superficial, perivascular infiltrates composed of lymphocytes and histiocytes. These changes were consistent with our clinical diagnosis of Darier's disease (keratosis follicularis). Figure 3. Corps ronds (large arrow) and focal acantholysis with suprabasal clefts (small arrow) are present in the epidermis (hematoxylin and eosin; original magnification, ×,40) [source]

The Return of the Common Bedbug

PEDIATRIC DERMATOLOGY, Issue 3 2005
Maryanna C. Ter Poorten M.D.
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.
