Tuberculous Flexor Tenosynovitis with Median Nerve Compression: A Case Report.

CASE: A 65-year-old female patient presented with complaints of diffuse pain and swelling in her right wrist with paresthesia in her right hand with thenar wasting. Her magnetic resonance imaging scan was suggestive of flexor tenosynovitis of the wrist with compression of the median nerve with multiple rice bodies. She underwent excisional biopsy along with median nerve decompression. Mycobacterium tuberculosis was detected by polymerase chain reaction (GeneXpert), and histopathology identified caseous granulomas. The patient was started on antitubercular chemotherapy postoperatively. CONCLUSION: In endemic countries such as India, tuberculous flexor tenosynovitis must always be a differential diagnosis in cases of wrist swelling with rice bodies.

Presentation of Colorectal Carcinoma as Abdominal Wall Phlegmon.

Colorectal cancer (CRC) is the third most common malignancy and the second most common deadly cancer worldwide as of 2020. Unusual presentation of this cancer with locally advanced disease is rare and seen in only 5% to 22% of cases. We present the case of a 53-year-old male who had invasive cecal adenocarcinoma with phlegmon of the abdominal wall musculature at presentation and an aggressive course that did not respond to the standard lines of therapy. In the current era of ongoing tremendous developments in colorectal cancer diagnosis and treatment, this uncommon case reminds us that locally advanced CRC is still a challenge to manage. Precision medicine with treatment strategies tailored to an individual's genetic, environmental and lifestyle factors is the current need.

Apical lung mass-A rare presentation of multiple myeloma.

Multiple myeloma is a neoplastic proliferation of immunoglobulin-producing plasma cells with clinical features resulting from infiltration of plasma cells into bones and other organs. Multiple myeloma manifesting as an apical lung mass is less common and very few cases have been reported. We report the case of a 50-year-old female who presented with an apical lung mass which happened to be multiple myeloma arising from the upper ribs into the lung. At the time of diagnosis, patient had axillary lymph node metastasis with extensive bony involvement. This case report and literature review provides insight to a rare but significant presentation of multiple myeloma and highlights the need to consider multiple myeloma as a possible differential for Pancoast tumor in the appropriate clinical setting as this could potentially affect management options and patient outcome.

Lymphoplasmacytic Lymphoma with Only Lambda Light Chain Monoclonal Paraprotein Expression.

Introduction: Lymphoplasmacytic lymphoma (LPL) is a rare low-grade B-cell neoplasm that accounts for approximately 2% of all haematological malignancies. Most patients have the clinical syndrome of Waldenstrom macroglobulinemia (WM), which is defined as LPL with an associated immunoglobulin M (IgM) serum monoclonal protein. Roughly 5% of LPL patients secrete non-IgM paraproteins (e.g., IgG, IgA, kappa, lambda) or are non-secretory. Case description: We report the case of a 41-year-old woman who was diagnosed with non-IgM LPL with lambda light chain monoclonal paraprotein production and normal serum immunoglobulin levels. The MYD88 L265P mutation was detected on fluorescence in-situ hybridization (FISH) analysis of the bone marrow. The patient underwent treatment with a combination of ibrutinib and rituximab. There was an initial response but she died 8 months after diagnosis. Discussion: Non-IgM LPL poses diagnostic and therapeutic challenges to clinicians as it is an exceptionally rare malignancy with a heterogeneous clinicopathological presentation and scarce literature. Among non-IgM LPL cases, those with lambda light chain production are even more rare. To the best of our knowledge, none have been reported to date. The addition of MYD88 L265P testing to the diagnostic armamentarium of non-IgM LPL cases is advisable for potential therapeutic reasons. LEARNING POINTS: Our case report and literature review provide insight into non-IgM lymphoplasmacytic lymphoma (LPL), an extremely rare malignancy.Our case report highlights the importance of the need for new treatments for non-IgM LPL.

Thrombotic complications and anticoagulation in COVID-19 pneumonia: a New York City hospital experience.

Infection with SARS-CoV-2 (COVID-19) can cause prothrombotic complications. We aim to study the frequency of thrombotic complications and impact of anticoagulation on outcomes in hospitalized patients. We conducted a retrospective chart review of 921 consecutive patients admitted to our hospital with COVID-19. Patients were divided into four groups depending on whether they were on anticoagulation prior to admission, started anticoagulation during the admission, received prophylactic anticoagulation, or did not receive any anticoagulation. At the time of analysis, 325 patients (35.3%) had died, while 544 patients (59%) had been discharged resulting in inpatient mortality of 37.3%. Male sex, age > 65 years, and high D-dimer at admission were associated with higher mortality. Sixteen patients (1.7%) had venous thromboembolism confirmed with imaging, 11 patients had a stroke, and 2 patients developed limb ischemia. Treatment with therapeutic anticoagulation was associated with improved inpatient mortality compared with prophylactic anticoagulation alone (63% vs 86.2%, p < 0.0001) in patients requiring mechanical ventilation. Other outcomes such as rates of liberation from mechanical ventilation and duration of mechanical ventilation were not significantly impacted by the type of anticoagulation.
