Ovarian vein thrombosis is a rare condition associated with the postpartum state, pelvic disease, gynecological surgeries, and other thrombophilic states. We present the first reported case of right ovarian vein thrombosis (OVT) in the setting of Coronavirus disease 2019 (COVID-19) unrelated to pregnancy, pelvic disease, or surgery. This case highlights the breadth of the hypercoagulable state induced by COVID-19. We also put forward the use of novel oral anticoagulants in the case of OVT.

Primary thyroid lymphoma, although a rare malignancy, can arise in common chronic inflammatory conditions such as Hashimoto’s thyroiditis. Incidental finding of a thyroid nodule with chronic thyroid inflammation warrants further investigation. Early detection of malignancy can play a vital role in improved outcomes. We report a case of a 60-year-old male who presented to the clinic for a routine visit. An enlarged, firm, non-tender thyroid gland was appreciated on exam with high thyroid stimulating hormone (TSH) level. Fine needle aspiration of the mass revealed nonspecific atypical lymphocytes. The pathology and immunohistochemical stains were consistent with histologic impression of extra nodal marginal B-cell lymphoma (mucosa-associated lymphoid tissue [MALT] lymphoma) and Hashimoto’s thyroiditis. Patient was treated with thyroxine after complete surgical excision of left thyroid lobe and remains in remission with close follow-up with his primary care provider. Primary thyroid MALT lymphoma follows an indolent process and remains asymptomatic in most patients. These are usually found to arise at sites of ongoing chronic inflammation with underlying autoimmune or infectious etiologies. Treatment modalities include surgical excision and/or radiation therapy for localized lesions, with both radiation and chemotherapy indicated for disseminated disease.

Myeloproliferative neoplasms such as essential thrombocythemia (ET) have been associated with glomerular disease on rare instances. A case of ET associated with immunoglobulin A nephropathy (IgAN) is described in a 57-year-old man with a history of hypertension. Progressively worsening renal function was noted in the patient along with unexplained mild thrombocytosis. Pathological review of renal biopsy identified IgAN concurrently with newly diagnosed JAK2-mutated ET. The patient was started on aspirin therapy and closely monitored for his renal function. A literature review of the association of ET and renal disease revealed nine cases of ET associated with IgAN, focal segmental glomerulosclerosis, and fibrillary glomerulonephritis. Comparison of the pathological features of the renal biopsies within the cases noted mesangial proliferation as a common finding, which has been described to be potentiated by platelet-derived growth factor (PDGF). This commonality may represent a link between ET and glomerular disease which deserves further attention in future cases. Improved management of such cases depends on the recognition of the combined occurrence of ET and glomerular diseases and uncovering the shared pathogenesis between platelets and glomeruli.

We report a case of an elderly Caucasian male with past medical history of dextrocardia with situs inversus totalis, polymyalgia rheumatica, history of cryptogenic stroke, and severe mitral regurgitation with mitral valve prolapse, who presented with acute heart failure symptoms, including severe dyspnea on exertion and worsening lower extremity edema in the setting of immunosuppression with steroids for a year-old diagnosis of polymyalgia rheumatica. One month prior to this presentation, the patient suffered a transient ischemic attack and during the workup, his transthoracic echocardiography showed myxomatous degeneration of posterior mitral leaflet, partially flail, with severe mitral regurgitation, which required mitral valve replacement. Genome sequencing of mitral valve anterior leaflet pathology detected Tropheryma whipplei as a causal agent of culture-negative endocarditis. The patient was treated with 6 weeks of ceftriaxone and ampicillin–sulbactam and further continued trimethoprim–sulfamethoxazole for 1 year. He continued antibiotic treatment with resolution of shortness of breath along with arthralgia.
