The triad of rash, arthritis, and uveitis seems to be characteristic for early-onset childhood sarcoidosis. We describe an interesting case of early-onset childhood sarcoidosis coexisting enchondromatosis, which clinically masquerade as Langerhans cell histiocytosis. A 33 months old girl presented with skin rash, subcutaneous nodules with polyarthritis, and revealed the involvement of lymph nodes as well as spleen during work-up. She also presented with multiple osteolytic lesions which pathologically proven enchondromatosis. Oral prednisone was prescribed at 2 mg/kg/day for 2 months until when subcutaneous nodules and joint swellings almost disappeared, and then slowly tapered over a period of 5 months. We report an unusual case of early-onset childhood sarcoidosis presented with osteolytic bone lesions which were irrelevant to sarcoidosis.

Sarcoidosis is a systemic granulomatous disease of unknown etiology that involves many organs, occasionally mimicking malignancy. We herein report a 50-yr-old woman of muscular sarcoidosis of chronic myopathic type, manifested by hypercalcemia and muscle wasting. Besides insignificant hilar lymphadenopathy, her sarcoidosis was confined to generalized atrophic muscles and therefore, F-18 FDG PET/CT alone among conventional imaging studies provided diagnostic clues for the non-parathyroid-related hypercalcemia. On follow-up PET/CT during low-dose steroid treatment, FDG uptake in the muscles disappeared whereas that in the hilar lymph nodes remained. PET/CT may be useful in the evaluation of unexpected disease extent and monitoring treatment response in suspected or known sarcoidosis patients.

PURPOSE: We report the case of a patient with scar sarcoidosis that developed along a previous eyelid scar. There was no evidence of ocular or systemic sarcoidosis. METHODS: A 29-year-old man presented with a mass on his right eyelid that had been present for two month. On ocular examination an erythematous, firm, and non-tender mass was diffusely palpable along the upper and lower eyelid scar. We performed an incisional biopsy of the lower lid mass. RESULTS: Histopathologic examination of the mass revealed numerous, noncaseating granulomas with multi-nucleated giant cells. The giant cells contained asteroid bodies and calcium oxalate crystals characteristic of sarcoidosis, although the patient had no other evidence of systemic sarcoidosis. The mass in the upper lid disappeared after intralesional triamcinolone injections. CONCLUSIONS: This case represents a rare occurrence of sarcoidosis that arose in an old eyelid scar. Scar sarcoidosis should be considered in the differential diagnosis of an unusual mass in a scar.
