The Kveim-Siltzbach (KS) skin test has been in use worldwide for fifty years. It is a safe, simple and specific out-patient technique to confirm the diagnosis of sarcoidosis and to provide evidence of activity of the disease. It is most helpful in delineating sarcoidosis as a cause of erythema nodosum, uveitis, liver granulomas, hypercalciuria and meningitis. It is the patient's preference when he is confronted with the choice between a skin test or alternatively bronchoscopy, lung biopsy or aspiration liver biopsy. It also creates considerable academic interest for it reflects granuloma formation vividly when viewed by modern immunopathology techniques. Its disadvantage is that it takes a month to provide a result; a critical month in which systemic steroids are avoided for this would suppress the test. The immunopathology of the KS test is similar to spontaneous sarcoid granuloma formation, and evolution of the KS granuloma may provide clues to the cause of sarcoidosis and other granulomatous disorders.

Twenty-eight cases of sarcoidosis in children 4 years of age or younger have been reported in the literature, including the case presented herein. These patients may display a distinct aspect of this disease. Half of them are younger than 1 year and all but two are whit. Clinically, they are different from the older children: they lack pulmonary disease, and they predominantly have uveitis, arthritis, and skin rash. The natural history of the disease not only involves chronic arthritis, but has the potential for renal disease secondary to hypercalciuria. Use of adrenocorticosteroids may be effective in these situations, as well as for eye involvement.

The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

Sarcoidosisis amultisystemic granulomatous disease, potentially affecting any organ system of the body. Calcium metabolism disturbances occur in up to 20% of patients, of which hypercalciuria and asymptomatic hypercalcemia are most common. Ocular sarcoid typically presents with anterior chamber manifestations such as uveitis, iritis, and iridocyclitis, but can involve posterior chamber as well. We describe herein a unique presentation of sarcoidosis with retinal detachment and symptomatic hypercalcemia as its first manifestation. Prompt therapy with steroids is indicated in these cases, and an immediate ophthalmology referral cannot be overemphasized.
