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.

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.

Introduction: Primary vaginal malignant melanomas are rare tumours with a limited number of cases published in the literature. They primarily affect post-menopausal women with a median age of 57–68 years and have a dismal prognosis. The 5-year survival rate, regardless of treatment, is approximately 5–25%. Case description: We present the case of an 87-year-old female who presented with haematuria and urinary incontinence. She was diagnosed with AJCC stage IIIC vaginal melanoma. Considering her age and the extent of malignancy, surgery was not a viable option and immunotherapy with nivolumab and ipilimumab was initiated as treatment. Discussion: The diagnosis of vaginal melanomas includes pathological analysis and immunohistochemistry (IHC) of the mass, imaging to determine extent, and genetic testing. Surgery is the preferred treatment in suitable cases. For metastatic or unresectable cases, immunotherapy or targeted therapy is the preferred first-line treatment. Due to the lack of an adequate number of cases to conduct randomized clinical trials, prognostic factors and treatment protocols for vaginal melanomas are not clearly defined. At present, the management of these tumours is largely based on retrospective studies and anecdotal evidence accompanied by significant knowledge gaps. Our case will be a valuable addition to the existing literature on vaginal melanomas that are managed non-surgically.

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.
