Abstract:
A 54-year-old woman presented with a five-year history of malaise with weight loss and arthralgia of both knee joints. Six months prior to the presentation, an indurated nodule developed at the site of an old scar on the temporal side of left eyebrow. Subsequently, erythema and nodules spread over the trunk and extremities, especially at the sites of old scars on the hands. Physical examination showed bilateral axillary lymphadenectasis, a plaque at the site of an old scar on the temporal side of left eyebrow, a subcutaneous mass at the extensor aspect of the right upper arm, multiple dark-erythematous nodules at the site of scars on the left hand and both soles, few small erythematous papules scattered on the left forearm and trunk. The serum angiotensin converting enzyme concentration was high (82 kU/L). Computer tomography of thorax showed multiple obscure tubercles in both lungs and swollen lymph nodes in mediastina and axillary fossa, but no hilum pulmonis lymphadenectasis was observed. Histopathology revealed non-caseating granulomas with multinucleated giant cells. Neither acid-fast bacilli nor PAS staining was positive. A diagnosis of scar sarcoidosis was established. The lesions obviously improved after one-month treatment with oral methylprednisolone. This case represents a rare subtype of sarcoidosis that arose in old sears and clinically manifests as scar, nodules,plaques, subcutaneous masses and papules. The reactivation of old scars, which manifests as erythematous swelling and nodules, may highly suggest the diagnosis of sarcoidosis.
