RESUMO
Sarcoidosis is a multisystem inflammatory disease involving granuloma formation. The exact etiology of the disease remains unknown. While the lungs are the most commonly involved organs in sarcoidosis, bone marrow-only involvement is quite rare. As bone marrow-only involvement can have a presentation that closely resembles multiple myeloma, a significant diagnostic dilemma can occur as the treatment for sarcoidosis is different compared to multiple myeloma. We present a case of a 62-year-old female who presented with worsening lower extremity weakness and fatigue. She was found to have new-onset hypercalcemia, normocytic anemia, and lytic bony lesions. Extensive laboratory workup for multiple myeloma was negative with bone marrow biopsy showing non-caseating granulomas, thus diagnosing the patient with sarcoidosis involving the bone marrow.
RESUMO
Vogt-Koyanagi-Harada disease is a multisystem autoimmune inflammatory disorder that affects the eyes, ears, skin, and the nervous system. It is a rare disease that mainly affects Asian, Hispanic, and Middle Eastern populations. Systemic steroids and immunosuppressants are frequently used to treat autoimmune diseases like this. Despite the fact that they reduce morbidity, immunosuppressants can have a number of side effects and are difficult to use, particularly when treating uncommon autoimmune illnesses. We present a case of a 56-year-old man who visited our health facility complaining of increased tears in both eyes along with bilateral blurring of vision. He was subsequently identified as having Vogt-Koyanagi-Harada disease. After prednisolone and methotrexate failed to have the desired effect, he was treated with azathioprine, which caused pancytopenia, and manifested as fever with positive blood culture for a coagulase-negative staphylococcus infection. Keywords: case reports; pancytopenia; steroid.
