Fibrin microthrombi in bladder urothelium after SARS-CoV-2 infection: Case report

Abstract:

A 45-year-old male with diabetes, hypertension and hyperlipidemia was referred to urology due to persistent symptoms of urinary frequency, urgency, nocturia, erectile dysfunction, and constant pain localized to the bladder, pelvis, and perineal area, 3–4 months after SARS-CoV-2 infection. A bladder biopsy showed urothelial mucosa and submucosa with hemorrhage and fibrin microthrombi in blood vessels. Hydrodistention of the bladder and pelvic floor physical therapy resolved symptoms, though bladder and pain symptoms returned upon reinfection with SARS-CoV-2. Urinalysis revealed elevated urinary interleukin-8, which may indicate localized bladder inflammation.

Histopathology of Persistent Long COVID Toe: A Case Report

Abstract:

During the 2020 coronavirus (SARS-CoV-2) pandemic, several cutaneous lesions were identified, including: pseudo-chilblain, vesicular, urticarial, maculopapular, and livedo/necrosis. A 59-year-old obese man with probable COVID-19 developed painful cyanosis with histopathologic capillary thrombosis of toes, and the cyanosis persisted for nearly 22 months. Shortly after initial exposure to family members with documented SARS-CoV-2, he developed upper respiratory symptoms, yet his anti-SARS-CoV-2 antibody and nasal swab RT-PCR tests were repeatedly negative. Two family members were hospitalized and one of them succumbed with documented SARS-CoV-2 pneumonia within ten days of exposure. Biopsy of the distal toe 16 weeks after initial exposure demonstrated papillary dermal capillary thrombosis with endothelial swelling, telangiectasia, and peri-eccrine lymphocytic infiltrates resembling pernio. Overall, this is the first case of biopsy of “long COVID toe” following presumed SARS-Cov-2 exposure, with demonstration of thrombotic vasculopathy, toe cyanosis, and pernio-like pathology.
