Destructive granuloma annulare of the skin and underlying soft tissues--report of two cases.

Clin Exp Dermatol

Department of Dermatology, Mayo Clinic, Rochester, MN 55905.

Published: May 1991

Two cases of extensive cutaneous granuloma annulare (GA) associated with severe deformity and impairment of function in the involved extremity are described. In the first patient a mutilating, destructive arthritic condition and infiltrative oedema of upper extremities developed over the years along with florid disseminated GA of the tendons and overlying skin. In the second patient disseminated GA of one lower extremity resulted in diffuse induration and chronic lymphoedema. In both cases, histology showed palisading granulomas typical of GA at all levels of the dermis, subcutaneous tissues, fascia, and synovium. The unique clinical features of GA in both presented cases emphasize the local destructive potential and, as yet, poorly understood progression of GA to a soft-tissue disease.

Syphilis, known as "the great mimicker," is caused by the spirochete Treponema pallidum and is characterized by a diverse array of clinical and histopathologic presentations. In secondary cutaneous syphilis, the most consistent morphological features include a superficial and deep perivascular infiltrate containing plasma cells, varying degrees of endothelial swelling, irregular acanthosis, elongation of rete ridges, a vacuolated pattern, and the presence of plasma cells. Although serologic tests are essential for definitive diagnosis, spirochetes can sometimes be directly identified in silver-stained tissue slides or through immunohistochemistry.

Leprosy, or Hansen's disease, is an ancient infectious disease characterized by varied clinical presentations influenced by the host's immune response. This study aimed to explore the atypical manifestations of Hansen's disease in a cohort of 15 biopsy-confirmed patients admitted to the Department of Dermatology, Venereology & Leprosy at a tertiary care center in Andhra Pradesh, India. There were 14 male patients and one female patient, with a mean age of 42.

Article Synopsis
  • Granuloma annulare (GA) is a non-infectious skin condition that can become widespread in some patients; this study focused on those with disseminated GA in a German hospital.
  • A total of 239 patients were studied, with 33 having confirmed disseminated GA, predominantly affecting women around the age of 57, and many reporting little to no symptoms.
  • Treatment options included glucocorticoids and phototherapy, but only a small percentage achieved remission, highlighting the need for more effective clinical trials for new therapies.
