Unilateral lower limb atrophy associated with glomus tumors: a case report

Traditional cheese consumption leading to hemodialysis induced by rifampin treatment: A case report

This case report details the journey of a 51-year-old man residing in a remote Iranian village, involved in livestock rearing, who was hospitalized due to Brucellosis contracted from consuming traditional cheese and dairy products. Initially treated with doxycycline and rifampin, complications arose during antituberculosis therapy, with the patient developing symptoms of nausea, vomiting, and edema alongside renal function deterioration necessitating medication cessation. Subsequent manifestations of proteinuria, toxic hepatitis, and nephrotic syndrome prompted renal biopsy, revealing drug-induced glomerular and tubular damage. Swift cessation of rifampicin, combined with prednisolone therapy, led to symptom amelioration, resulting in the cessation of dialysis and the patient's discharge within three weeks. This case underscores the intricate relationship between traditional cheese consumption, medication-induced renal complications, and the importance of timely intervention and appropriate management in achieving a successful patient outcome.

Unilateral Calf Atrophy: A Case Series of Clinical and Electrodiagnostic Findings With a Review of the Literature

Unilateral calf atrophy may result from several medical conditions, such as lumbar radiculopathy, asymmetric myopathy/dystrophy, a Baker's (popliteal) cyst leading to tibial nerve compression, and disuse atrophy. We present a case series of four patients with unilateral calf atrophy, including chronic neurogenic atrophy (benign focal amyotrophy, one patient), tibial nerve compression at the popliteal fossa by a Baker's cyst (one patient), and disuse atrophy (two patients). All four patients underwent electrodiagnostic (EDX) studies, and two of them had denervation changes of the gastrocnemius. One patient underwent an ultrasound (US), which revealed a large cyst in the popliteal fossa causing compression of the tibial nerve. The differential diagnosis of unilateral calf atrophy as well as diagnostic techniques to confirm the underlying pathology are described. EDX and US studies are useful in differentiating between the varied conditions that may cause asymmetric calf muscle wasting.

Glomus Tumor of the Lower Extremity Previously Misdiagnosed as Complex Regional Pain Syndrome in Close Proximity to a Myxofibrosarcoma: A Case Report

Complex regional pain syndrome (CRPS) is a potentially devastating condition that can result in severe psychological and social morbidity. It is a diagnosis of exclusion, and other pathologic entities must be ruled out first. Glomus tumors are exquisitely painful benign vascular tumors that are most common in the hand and are rarely found in the lower extremity. Here, we present a case of a patient who developed a focus of severe anterior knee pain and tenderness a few months after a car accident that had been misdiagnosed as CRPS for 15 years. She coincidentally developed a sarcoma of her ipsilateral leg distal to this site. Magnetic resonance imaging of the sarcoma included the area of knee pain where, interestingly, it identified a separate small soft-tissue mass. A glomus tumor was diagnosed histologically in a needle biopsy specimen from this mass, which was resected along with the sarcoma. For the first time in 15 years, despite the additional sarcoma surgery, she reported relief of her pain and complete resolution of her “CRPS.”
