Pancreatic Plasmacytoma: A Rare Extramedullary Manifestation Of Multiple Myeloma, Justin Robbins, Md, Gregory Habig, Md

The Medicine Forum

Multiple myeloma is a plasma cell dyscrasia in which neoplastic plasma cells pathologically produce monoclonal immunoglobulin and infiltrate bone marrow throughout the skeletal system. The disease is classically characterized by bone pain caused by lytic bone lesions, marked increases in monoclonal antibodies in blood or urine, hypercalcemia, and other systemic signs and symptoms of malignancy including weight loss and night sweats. A rare variant of multiple myeloma presents with extramedullary plasmacytomas, or plasma cell tumors, which arise in organs outside of the bone marrow¹. The case presented here exhibits this disease variant, with a woman with severe multiple …

A Rare Presentation Of A Clear Cell Variant Of Peritoneal Mesothelioma, Nivethietha Maniam, Md, Michael Lee, Md, Mihir M. Shah, Md, H. Richard Alexander, Md

The Medicine Forum

Primary malignant peritoneal mesothelioma with clear cell subtype is a rare malignancy with few previously reported cases. We present a 63-year-old female who presented with abdominal distention and was diagnosed with clear cell mesothelioma of the peritoneum with an isolated metastasis to the liver. The patient underwent surgical resection of a greater than 50 cm mass with en-bloc partial liver and gastric resection with an uneventful post-operative course. There are established prognostic and treatment recommendations for peritoneal mesothelioma based on histological subtype and patient-specific factors, although they do not explicitly incorporate clear cell subtype. This case report describes the presentation, …

A Slow Burning Diagnosis: A Case Report Of Hemophagocytic Lymphohistiocytosis Preceding The Diagnosis Of Subcutaneous Panniculitis-Like T-Cell Lymphoma, Steven Manobianco, Md, William Bradford, Md, Ida Micaily, Md, Adam Binder, Md

The Medicine Forum

HLH is a severe inflammatory syndrome characterized by primary or secondary immune dysregulation causing excess activation of macrophages and cytotoxic lymphocytes, leading to multi-system dysfunction. Diagnosing and managing HLH can be challenging for clinicians, with HLH-2004 criteria for diagnosis requiring a molecular diagnosis or the presence of at least five of the following: fever, splenomegaly, cytopenia involving two or more cell lineages, hypertriglyceridemia and/or hypofibrinogenemia, hemophagocytosis in the bone marrow, spleen or lymph nodes with no evidence of malignancy, low or no NK cell activity, elevated ferritin, or elevated soluble IL-2 receptor¹. These criteria have been utilized to …

Hemothorax And Hemorrhagic Ascites: A Rare Presentation Of Endometriosis, Harry Wang, Md

The Medicine Forum

Introduction

Endometriosis is a common diagnosis in reproductive age women characterized by the presence of endometrial tissue outside the uterine cavity.1 Although it is typically confined to the pelvis, rare manifestations involving the thorax, abdomen or pericardium have been documented.2-5 Even more rare is the concurrent presence of endometriosis- associated hemorrhagic pleural effusion and ascites, which can prove a diagnostic challenge. We describe a case of hemothorax and hemorrhagic ascites in a woman with shortness of breath and abdominal pain.

Hyperviscosity In Non-Igm Lymphoplasmacytic Lymphoma, Mario Fonseca-Paricio, Md, Sushil Chmire, Md, Adam Binder, Md

The Medicine Forum

The following is a case of how a non-IgM paraproteinemia can present with symptoms of hyperviscosity and coagulopathy, an uncommon occurrence.1-3 As this case demonstrates, this diagnosis must be considered even in patients with relatively normal coagulation laboratory results. Such pathology requires urgent treatment with plasmapheresis.

Worsening Autoimmune Neutropenia After Stopping Ibrutinib In A Patient With Chronic Lymphocytic Leukemia: Case Report And Review Of Literature, Natalie Rosen, Ba, Thomas Klumpp, Md, Sameh Gaballa, Md, Msc

The Medicine Forum

Introduction

Autoimmune cytopenia (AIC) is relatively common in patients with chronic lymphocytic leukemia occurring in 5-10% of patients during the course of their disease.1 Autoimmune hemolytic anemia (AIHA) constitutes the highest prevalence (5-10%) of CLL-associated AIC followed by idiopathic thrombocytopenic purpura (ITP) (2-5%), pure red cell aplasia (PRCA) (<1%), and autoimmune neutropenia (AIN) (<1%).2,3 The prevalence of AIN, however, may in fact be higher than reported due to a lack of awareness of the condition and difficulty in its diagnosis.4 Despite its rarity, autoimmune neutropenia can be a significant clinical challenge in patients with CLL and can increase the risk of infectious complications. Thus, the prompt diagnosis and resolution of CLL-associated AIN is essential to the management of these patients.

Ibrutinib is a selective inhibitor of Bruton tyrosine kinase and induces a durable response in patients with CLL.5 The activity of ibrutinib in CLL-associated AIC is largely unknown as pivotal clinical trials excluded patients with AIC. We report a case of a patient with CLL who experienced worsening of AIN after …

Bilateral Choroidal Metastases As Initial Presentation Of Widespread Follicular Thyroid Cancer, Jennifer Hong, Md

The Medicine Forum

Introduction

Follicular thyroid cancer (FTC) is the second most common malignancy of the thyroid gland and comprise 10-15% of all thyroid tumors; the usual mode of spread is via hematogenous dissemination with the most common sites of metastases being the lungs and bones.4 A case is presented to demonstrate the unusual presentation of follicular thyroid cancer as bilateral choroidal metastases. Although exceptional, a diagnosis of choroidal metastases should be considered in any decline in visual acuity in patients with thyroid cancer.

Case Report: Pthrp Related Hypercalcemia In Diffuse Large B-Cell Lymphoma, Ankita Mehta, Md, Evan Caruso, Md

The Medicine Forum

INTRODUCTION

Hypercalcemia is commonly associated with solid tumor malignancies, but less often with hematologic malignancies. When present in hematologic malignancies, hypercalcemia is often secondary to overproduction of Vitamin D from the tumor cells. Very few cases with parathyroid hormone related peptide (PTHrP) induced hypercalcemia in B-cell lymphomas have been reported. Here we present a 44 year old male with a history of chronic lymphoctic leukemia who presented with hypercalcemia and an elevated PTHrP, found to have a transformation to Diffuse Large B-cell Lymphoma (DLBCL).

Anorectal Melanomas: Case Series, Jinyu Zhang, Md, Matthew Sochat, Md, Edward R. Feller, Md

The Medicine Forum

INTRODUCTION

Melanoma is the most common tumor to metastasize to the gastrointestinal (GI) tract. 60% of patients who die with malignant melanoma have GI involvement at autopsy1. Symptomatic disease presenting during life is unusual. Anorectal melanoma, a rare tumor that represents 1% of all melanomas and less than 4% of all anal malignancies, manifests with a range of non-specific symptoms and physical exam findings2. In fact, about one-third of lesions may be amelanotic3,4. Initial misdiagnosis as a benign lesion such as hemorrhoid is common.

We report 3 cases of anorectal melanoma presenting as primary GI complaints all without known cutaneous …

Case Report: Uncontrolled Anasarca: Capillary Leak Syndrome, Ankita Mehta, Md, Mansi Shah, Md

The Medicine Forum

INTRODUCTION

Capillary leak syndrome (CLS) is a rare clinical disease that causes edema, hypoproteinemia, episodic hypotension, dyspnea, hyponatremia, and weight gain that can be life threatening1. Although the underlying pathology is currently unknown, CLS is thought to be secondary to a systemic process associated with hyperpermeability of the body's microcirculation, resulting from a diffuse and severe disruption of the endothelium and causing generalized edema and often acute respiratory distress2.
