Case Report: Tuberculosis-Induced Autoimmune Hemolytic Anemia.

Tuberculosis (TB) is an infectious disease that affects different organs, causing multiple complications, including hematological sequelae. One of the most common TB-hematological complications is anemia of chronic disease. Very rarely autoimmune hemolytic anemia (AIHA) has been reported as an uncommon manifestation of TB. In this case, we present a female who presented with refractory AIHA, which was attributed to disseminated TB. The patient responded well to steroids, anti-TB medications, and rituximab.

Isolated Oculomotor Cranial Nerve Palsy as Unusual Presentation of Primary High-Grade Burkitt's Cell Lymphoma in HIV Patient: Case Report and Literature Review.

Burkitt lymphoma (BL) is a highly aggressive B-cell neoplasm that is well known to be associated with HIV. The presentation usually reflects the underline immunodeficiency state (like opportunistic infections and chronic diarrhea, and enlarged lymph nodes). The most common causes for 3rd cranial nerve palsy are intracranial aneurysm, ischemia, trauma, and migraine. But for our case, it turned out to be associated with underline HIV and BL, which is an unusual cause. Here, we present a 43-year-old gentleman with no past medical history presented to the emergency department with 4 days history of drooping of left eyelid and headache and binocular diplopia with no other neurological features. CT abdomen showed lymph node enlargement. Lymph node biopsy showed the characteristic of Burkitt's cell lymphoma. He was started on chemotherapy, but unfortunately, he died. We're enlightening this case of an isolated oculomotor nerve palsy to diagnose lethal pathology like disseminated BL.

Low back pain in beta thalassemia major revealing sacral extramedullay hematopoeisis: A case report.

Extramedullary hematopoiesis (EMH) is a well-known complication of beta thalassemia major and frequently occurs in typical sites such as liver or spleen. However, when presenting in unusual sites as sacrum, other diagnosis should be excluded by histopathology prior to deciding on treatment plan.

Tocilizumab-induced cytomegalovirus colitis in a patient with COVID-19.

The authors urge clinicians to observe for early signs of CMV reactivation in patients presenting with gastrointestinal bleeding and intestinal perforation after receiving tocilizumab or other immunosuppressive therapy as a treatment for COVID 19. Early recognition of CMV infection and treatment will prevent life-threatening bleeding and mortality.

Subcutaneous Masses as an Unusual Manifestation of Relapse in a Case of Atypical Chronic Lymphocytic Leukemia with Prolymphocytoid Transformation and Complex Karyotype: A Diagnostic Dilemma and Treatment Challenge.

BACKGROUND Most patients with chronic lymphocytic leukemia (CLL) are asymptomatic at diagnosis, but 10% present with B symptoms. Most patients have palpable lymphadenopathy, while 20-50% of the patients have hepatosplenomegaly. Cutaneous infiltrations in patients with CLL can be localized or generalized in the form of erythematous papules, plaques, nodules and, ulceration, which is uncommon. CASE REPORT We present the case of a 71-year-old man diagnosed with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with atypical immunophenotype and increased prolymphocytes (CLL/PLL), which was treated initially after white blood counts (WBC) doubling with Bendamustine and Rituximab for 6 cycles, and achieved complete remission. The patient relapsed after 6 months of completion of treatment, with multiple large subcutaneous masses, proved to be infiltration with the same atypical CLL/SLL on tissue biopsy, with pathologic features indicating disease progression. The lack of similar reported cases, and the aggressiveness of the tumor clinically and histopathologically, resulted in the decision to treat with Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, and Prednisolone (R-CHOP) as a case of aggressive lymphoma, with complete remission clinically and radiologically. CONCLUSIONS We present a rare case of subcutaneous extramedullary masses of atypical CLL/SLL. The high proliferation index (Ki-67) and the increase of large cells are suggestive of aggressive progression of the disease; however, no frank features of Richter's transformation were noted. Based on this and because of the unusual aggressive-looking skin masses, the panel decided to treat the patient with R-CHOP. The impact of this presentation on the prognosis of the disease is not clear. To date, our patient has responded well to treatment with R-CHOP, with complete remission of the subcutaneous masses and on PET scan, but further follow-up is needed.
