Rare Coagulopathies in Hematologic Spotlight: Isolated Factor V Deficiency and Combined Factor V and VIII Deficiency.

Rare coagulation disorders pose significant diagnostic challenges emphasizing the importance of clinical vigilance and meticulous hemostatic workup for accurate diagnosis and timely management. We present two cases of exceptionally uncommon coagulopathies - isolated factor V deficiency (F5D) and combined factor V and VIII deficiency (F5F8D). Case 1 features a 24-year-old woman incidentally diagnosed with severe F5D during routine preoperative evaluation for an ovarian cyst.

Preliminary Cytomorphologic Diagnosis of Hematolymphoid Malignancies in Effusions: A Cyto-histo Correlation with Lessons on Restraint.

Background: Effusions as part of hematologic neoplasms are rare and as a primary presentation, rarer. In standalone laboratories of developing countries, resorting to techniques such as flow cytometry or immunohisto/cytochemistry may not be possible. A near definitive diagnosis on cytomorphology would, therefore, be an ideal beginning.

Primary Intraocular Malignant Rhabdoid Tumor Mimicking Retinoblastoma in a Child.

Primary rhabdoid tumors are highly malignant, rare tumors occurring in the renal, extrarenal soft tissue or central nervous system. They have non-specific radiological features and present with several histological components that create a problem in differential diagnosis with other embryonal tumors. We report a rare case of malignant rhabdoid tumor of the retina that presented with clinical features like those of retinoblastoma.

Multifocal Superficial Rapidly Growing Postirradiation Sarcoma Mimicking Metastatic Carcinoma.

Radiation induced sarcomas (RIS) on cytology is rare however need to be reported as they are histologically distinct from the primary tumor and arise years after completion of the radiotherapy. Fine needle aspiration cytology is mostly indicated in cancer patients suspected of recurrence/metastasis and rarely in secondary tumors post therapy or irradiation. Depending on the morphology and site of occurrence of RIS they can cause diagnostic difficulty with the primary carcinoma or sarcoma that was irradiated.

Cardiac tamponade as an initial presentation of papillary carcinoma with psammoma bodies and intranuclear grooves-A diagnostic dilemma.

Involvement of body fluids by adenocarcinoma is a common phenomenon. However, metastasis to the pericardial fluid by adenocarcinoma is a rare occurrence. The most common malignancies associated with malignant pericardial effusion are carcinoma of the lung, breast, esophagus, melanoma, lymphoma, and leukemia.
