A 60-Year-Old Woman with Symptoms of Combined Carpal Tunnel Syndrome and Cubital Tunnel Syndrome Due to an Elastofibroma Causing Compression of the Median and Ulnar Nerves.

BACKGROUND Cubital tunnel syndrome results from pressure or stretching of the ulnar nerve, and carpal tunnel syndrome involves the median nerve. Elastofibroma is a rare, benign, slow-growing soft-tissue tumor that commonly occurs as a bilateral infrascapular tumor in elderly women. This report is of a 60-year-old woman who presented with combined carpal tunnel syndrome and cubital tunnel syndrome due to an elastofibroma causing compression of the median and ulnar nerves. CASE REPORT We report the case of a 66-year-old woman with left-hand numbness, tingling along the fingers, sleep disturbance, and weakness in pinching or holding objects for an extended period. The clinical examination and nerve conduction studies established the diagnosis of combined carpal tunnel syndrome (CTS) and cubital tunnel syndrome (CuTs) complicated by intrinsic muscle wasting. The patient underwent left carpal and cubital tunnels release surgery and end-to-side anterior interosseous nerve transfer to the motor component of the ulnar nerve. Pathologic evaluation of the entire specimen showed collagen bundles alternating with refractive cylinders stained with Verfoeff-van Gieson elastic stain. CONCLUSIONS This report is of a rare case of a histologically-confirmed single, peripheral, benign elastofibroma involving compression of the ulnar and median nerves. This case highlights the importance of histopathology in diagnosing rare soft-tissue tumors arising at an uncommon site and presenting with rare symptoms.

COVID-19 Vaccine as a Potential Triggering Factor for Anti-Glomerular Basement Membrane (GBM) Disease: A Case Report and Literature Review.

Coronavirus 2019 (COVID-19) is considered one of the most significant medical pandemics of this century, with high morbidity and mortality associated with the pandemic. The virus was recognized initially as a cause of pneumonia, but subsequent studies showed significant association with gastrointestinal, neurological, and autoimmune diseases. By 2020, several vaccines became available for use, significantly reducing the infection rate. A good safety profile supported most of the studies related to vaccines. However, this area is still under study, and some reports linked the COVID-19 vaccine to the development of thrombocytopenia, thrombosis, Guillain-Barre syndrome, autoimmune diseases, and myocarditis. These side effects need to be reported to VAERS (Vaccine Adverse Event Reporting System). The exact etiology of anti-glomerular basement (Anti-GBM) disease remains unknown, but the disease is thought to be triggered by environmental factors in genetically predisposed individuals. It is considered one of the serious diseases that could lead to permanent kidney impairment if not treated early and adequately. That's why a great effort is being made by health care practitioners to figure out and avoid the risk and triggering factors. Few previously published papers linked the COVID-19 vaccine and the development of anti-GBM disease, which raised concerns about digging more into this area. Herein, we are reporting a case of a patient who developed rapidly progressive glomerulonephritis (RPGN) due to anti-glomerular basement membrane (GBM) antibody disease two days after receiving the second dose of the COVID-19 vaccine.

Primary bladder amyloidosis mimicking bladder cancer complicated by bladder rupture: A case report.

Amyloidosis is related to the extracellular deposition of abnormal protein fibrils in various tissues. It can be either localized to an organ or generalized, affecting multiple systems. Amyloidosis of the urinary bladder is a rare histopathological finding. It is clinically interesting that such cases' clinical, radiological, and even endoscopic presentation mimic urothelial carcinoma to a great extent. Here, we discuss a case of a 49-year-old gentleman who presented with frank painless hematuria. The patient was diagnosed with a bladder mass suspicious of malignancy depending on the clinical presentation aided by the cystoscopic and radiological evaluation. Histopathologic samples of the transurethral resection of the mass proved to be primary bladder amyloidosis. This case is of unique clinical interest in that it is the first case reported of bladder amyloidosis that is complicated by extraperitoneal bladder rupture post-operatively. However, no immediate intraoperative perforation to the bladder wall during resection was evidenced.

Water clear cell ectopic non-iatrogenic giant parathyroid adenoma in sternohyoid muscle with thyroid nodule and asymptomatic hypercalcemia due to primary hyperparathyroidism: Case report and literature review.

BACKGROUND: Ectopic parathyroid gland is not uncommon, and is associated with primary hyperparathyroidism. Giant parathyroid adenoma (PA) and concurrent presence of enlarged thyroid nodule increases the probability of ectopic location. The combination of a giant PA that is ectopic (within the strap muscle) in the neck is very rare, especially in cases with no previous surgery. The rare histopathological findings of the current case, water clear cell parathyroid adenoma (WCCPA), could explain the patient's presentation, since it has low endocrine function. CASE PRESENTATION: A 56-year-old Qatari female on routine visit to primary health care physician for hypertension, was incidentally discovered to be hypercalcemic and was referred to the emergency department of our institution. Neck ultrasound showed a thyroid nodule on the left side, but 99mTc-sestamibi scintigraphy identified a left PA. FNAC of the thyroid nodule showed that it was a colloid nodule. She underwent left hemithyroidectomy and excision of left PA. Intraoperatively, the PA was giant and in the sternohyoid muscle. Intraoperative monitoring of intact PTH (IOiPTH) confirmed successful excision. DISCUSSION: Ectopic giant parathyroid adenoma is rare especially with the intramuscular location in sternohyoid muscle in the neck without previous neck surgeries. The presence of thyroid nodule could be a precipitating factor for migration of the PA. Preoperative assessment with the radiological image is crucial for diagnosis but sometimes fail to localized the PA. CONCLUSION: Giant asymptomatic PA with long standing low function before hyperfunctioning should raise the suspicion of WCCPA. If diagnosis is confirmed, metastasis from a clear cell renal cell carcinoma should be ruled out.
