Twin Malignancy of Acute Myeloid Leukemia and Multiple Myeloma in a Chemotherapy-Naïve Patient: A Rare Occurrence.

Synchronous diagnosis of acute myeloid leukemia (AML) and multiple myeloma in chemotherapy-naïve patients is a rare event and poses a serious therapeutic challenge as it imparts a poor prognosis. We report a case of concurrent AML with multiple myeloma in a 44-year-old male along with a PUBMED-based research of previously reported similar cases in published literature.

Study of the Aetiology and Clinical Manifestations of Thrombocytopenia in a Tertiary Care Centre.

Introduction Thrombocytopenia is a commonly observed condition in clinical practice, and its diagnosis is often challenging due to numerous aetiologies and variations in clinical presentation. Early identification of thrombocytopenia and its causes can help prevent life-threatening haemorrhagic manifestations. Methodology A prospective observational study was conducted at a tertiary care hospital from February 2019 to January 2020. This evaluation aimed to determine the causes and prevalence of thrombocytopenia in a tertiary care setting. Patients aged 15 or older with a platelet count of fewer than 150,000/ µL were eligible for inclusion in this evaluation. Investigations for aetiology detection were recommended. Results During the one-year study period, a total of 100 patients, including 58 males and 42 females, with thrombocytopenia were selected for the study. The most common age group affected by thrombocytopenia in this study was between 46 and 55 years old. The most common clinical manifestations observed were generalised weakness (70%), haemorrhagic manifestations (60%), fever (50%), joint pain (37%), splenomegaly (35%), headache (30%), breathlessness (23%), lymphadenopathy (22%), hepatomegaly (24%), and abdominal pain (12%). The most prevalent causes of thrombocytopenia were megaloblastic anaemia (19 cases), dengue fever (15 cases), malaria (11 cases), enteric fever (nine cases), immune thrombocytopenia (ITP) (eight cases), and leukaemia (seven cases). Bleeding was reported as a symptom of thrombocytopenia in 60% of individuals in this study. Conclusion In the study, thrombocytopenia was more common in people aged 46-55 years, and males were more commonly affected than females. Megaloblastic anaemia and infectious disease were the most common causes of thrombocytopenia. Bleeding manifestations were found in 60% of patients with thrombocytopenia.

Clinico-Hematological Profile of Acute Leukemia Cases in Bihar: A Multiparameter Study in a Tertiary-Care Hospital.

Objective The actual incidence and demographic profile of hematological malignancies are unknown in Bihar because of lack of population-based cancer registry (PBCR) data and specialized tertiary cancer center facilities. The objective of this study was to estimate the prevalence, clinico-hematological profile and subtyping of acute leukemia cases by retrospective medical records. Materials and Methods A retrospective study was conducted in the Department of Hematology, Indira Gandhi Institute of Medical Sciences, Patna, Bihar, India, over 2 years from July 2019 to June 2021. A total of 176 cases with relevant clinical features and hematological findings were involved in the study. Medical records were studied and data were retrieved. Statistical Analysis Data were recorded and analyzed using SPSS version 25. Results A total of 176 cases with relevant clinical features and hematological findings were involved in the study. Acute myeloid leukemia (AML) was most prevalent (52.8%), followed by acute lymphoblastic leukemia (ALL) (34.1%) and unclassified acute leukemia cases (13.1%). Flow cytometry correlation was available in 150 cases. The ratio of males (62.5%) to females (37.5%) is 1.6:1. There was statistically significant difference in physical examination findings between AML and ALL patients. Splenomegaly, lymphadenopathy, and sternal tenderness were more often seen in ALL than in AML patients ( p < 0.05). Pallor was more significantly associated with AML than with ALL patients ( p < 0.05). Anemia and leucocytosis were found to be significantly associated with acute leukemia patients ( p < 0.000). Conclusion AML M2 was the most common subtype of AML, and B-ALL was the most common subtype of ALL cases.

Vancomycin-Induced Maturation Arrest with Reactive Promyelocyte Proliferation: A Diagnostic and Therapeutic Challenge.

Drug-induced leukopenia is a diagnostic and therapeutic challenge. A detailed clinical history is a must to come to a right diagnosis. Certain drugs are known to cause bone marrow suppression, leukopenia, myeloid maturation arrest, and reactive promyelocyte proliferation. Here, we report an unusual case of vancomycin-induced maturation arrest with marked promyelocyte proliferation in a 47-year-old male patient who was being treated for novel coronavirus disease 2019 (COVID-19) infection. Most times, this reactive promyelocyte proliferation is confused with neoplastic promyelocytes, leading to incorrect diagnosis and management.

Metastasis of primary signet ring cell carcinoma of prostate to bone marrow: A rare occurrence with review of literature.

We report a case of a 65-year-old male who presented with multiple enlarged intraabdominal lymph nodes with lytic lesions over pelvic and lumbar vertebrae. His serum prostate-specific antigen (PSA) was markedly raised. Bone marrow investigation revealed the presence of diffuse infiltration of single cells having hyperchromatic nuclei, moderate amount of eosinophilic cytoplasm, and eccentrically placed nuclei resembling signet ring cells. Hence, a diagnosis of metastatic signet cell carcinoma of prostate was made on bone marrow biopsy. This variant of prostatic carcinoma is very rare and accounts for only 2.5% of all prostatic adenoacarcinomas that make our case worth reporting. To emphasize the rare occurrence of this variant, we performed a Pubmed-based literature review of 25 years.

Endometrial stromal sarcoma with sex cord differentiation: An uncommon tumor posing diagnostic challenge.

Endometrial stromal sarcoma with sex cord differentiation is a very unusual neoplasm affecting the uterine cavity with an incidence of only 0.25%. They can cause difficulties in diagnosis due to it is histologic appearance and rarity of occurrence. Histopathological diagnosis still remains the cornerstone of diagnosis. Immunohistochemistry and molecular studies are also very helpful. We report a case of a 47-year-old patient who was diagnosed clinically and radiologically as intramural leiomyoma, but on histopathology examination and immunohistochemically proved to be endometrial stromal sarcoma with sex cord differentiation.

Primary pituitary tuberculosis.

Tuberculosis is an infectious disease that involves any organ. However, the primary pituitary tuberculosis is an extremely rare disease. Intracranial tuberculomas account for 0.15-5% of intracranial space-occupying lesions, of which, pituitary as the primary site is unusual, and easily misdiagnosed as pituitary adenoma. In this setting, the late diagnosis can result in permanent endocrine dysfunction. We report the case of a 50-year-old woman who presented to the neurosurgery outpatient department with complaints of progressively increasing headache and diminished vision over the last year. On the clinical examination, the patient was conscious and oriented. The routine hematological and biochemical workup showed an increased erythrocyte sedimentation rate (ESR) and increased prolactin levels. The radiological working diagnosis was consistent with pituitary macroadenoma. No other radiological and/or clinical clue that could elicit the suspicion of pulmonary or extrapulmonary lesions of tuberculosis was found. The transsphenoidal endonasal tumor excision was done. The histopathology showed numerous epithelioid cell granulomas, Langhans giant cells along with scant necrosis. Ziehl Neelsen staining demonstrated acid-fast bacilli, and the final diagnosis of pituitary tuberculoma was made. We report this rare case of pituitary lesion that may be included in the differential diagnosis of sellar lesions to avoid unnecessary surgical interventions, especially in regions where the disease is endemic.

Malignant glomus tumor of the index finger.

Glomus tumor (GT) is a benign mesenchymal tumor with an estimated incidence of 1.5 to 2% of soft tissue tumors. The majority of glomus tumors are benign and are mostly seen in the superficial skin & soft tissue of upper and lower distal extremity. The malignant variant of the glomus tumor is scarce. We report a case of a recurrent glomus tumor diagnosed in a 28-year-old male patient, who complained of painful swelling in the proximal phalanx of the right index finger. The magnetic resonance imaging of the hand revealed a well-defined multilobulated soft tissue mass at the palmar aspect of the 2nd digit along the shaft of the proximal phalanx. Histopathology revealed a well-circumscribed tumor arranged in solid sheets, nests and cords interconnect by vessels of varying size. The tumor cells were round to oval, showed moderate nuclear pleomorphism, eosinophilic cytoplasm, atypical mitoses (>5/10HPF), and necrosis. Immunohistochemically tumor cells reveal diffuse and strong cytoplasmic positivity with smooth muscle actin (SMA). Based on histomorphology and immunohistochemistry, a final diagnosis of malignant glomus tumor was made. We report this case due to its rarity, and it to be included among the differential if the lesion is painful and recurrent.

Endometrial and cervical osseous metaplasia with extramedullary haematopoiesis presenting as amenorrhea: Report of three cases.

Endometrial and cervical osseous metaplasia (OM) is a rare phenomenon seen mostly in reproductive age group. Patients generally present with complaints of secondary infertility. Although few cases of endometrial OM have been described in literature, to the best of our knowledge, only six cases of OM in cervix have been reported so far. We report three cases of endometrial OM with extramedullary hematopoiesis, presented with complaints of amenorrhea and secondary infertility. In addition, one of the patients also had cervical OM.

Cotyledonoid dissecting leiomyoma: an uncommon form of a common disease.

Leiomyomas are benign uterine smooth muscle neoplasms with varied morphology that are well known to undergo secondary changes. Cotyledonoid dissecting leiomyoma is a rare and distinct form of leiomyoma that poses a diagnostic challenge for clinicians, radiologists, and pathologists and can be confused with malignant uterine neoplasms. Only a few cases have been reported so far in the literature. Here we report a case of a cotyledonoid dissecting leiomyoma in a 60-year-old woman, emphasize its gross and histological features, and provide a review of the literature.
