A lady from Sudan was referred to our medical clinic as a case of cervical lymphadenopathy with gradual enlargement. She had no complaint. The not associated pain, fever, weight loss, cough, neither bleeding nor other swellings. There history chronic problems including TB and underwent thorough investigations LN biopsy. Lymphoma initially suspected. Fine-needle aspiration excision biopsy were u...

The recrudescence and modification of radiation effects precipitated by the use of chemotherapeutic agents has been reported extensively in the literature. The recall of quiescent radiation effects such as dermatitis, enteritis, esophagitis, pneumonitis, and mucositis has been most commonly associated with dactinomycin (actinomytin D) and doxorubicin (Adriamycin, Adria Laboratories, Columbus, O...

Measurement of cellular DNA content by flow cytometry demonstrated presence of two distinct aneuploid neoplasms in a patient who developed acute myeloblastic leukemia (AML) 4 mo after diagnosis of a diffuse histiocytic lymphoma (DHL). A lymph node aspirate contained peroxidase-negative, "null," hyperdiploid (2.6C) DHL cells, while the bone marrow (BM) contained 84% primitive peroxidase-positive...

Cytophagic histiocytic panniculitis is a rare disease, associated with either nonmalignant conditions or subcutaneous panniculitis-like T-cell lymphoma, and often also associated with hemophagocytic lymphohistiocytosis (HLH). We report the case of a 11-year-old boy with a history of secondary HLH who, after a local trauma, developed a painful, indurated plaque over the right thigh associated wi...

Serum LDH levels have been found to be significantly increased in non-Hodgkin lymphoma (NHL) patients, both histiocytic and lymphocytic. The duration of survival of NHL negatively correlates with the level of serum lactic dehydrogenase (LDH), and statistical analysis reveals that patients with lower levels of LDH have a longer survival rate than the patients with higher LDH activity, irrespecti...

Twenty-eight patients with previously untreated diffuse histiocytic lymphoma (DHL) were identified to be in pathologic stage (PS) I (11), IE (3), II (8), or IIE (6) by exploratory laparotomy and splenectomy. Six patients were treated with total nodal radiotherapy; 14 with an extended mantle; 5 with an inverted Y or whole abdomen; and 3 with an involved field. Twenty-six patients achieved a comp...

Eight new chromones, engyodontiumones A-H (1-8), and three new phenol derivatives (9-11) together with eight known polyketides (12-19) were isolated from the deep-sea-derived fungus Engyodontium album DFFSCS021. Their structures were identified by extensive spectroscopic analysis. Compounds 8 and 16 showed significant selective cytotoxicity against human histiocytic lymphoma U937 cell line with...

Light microscopical and routine immunohistochemical studies of a cervical neoplasm in a 32 year old woman initially suggested a histiocytic lymphoma, but histochemical staining for chloroacetate esterase established the correct diagnosis. This was supported by electron microscopic findings. Eight months later the patient developed a granulocytic sarcoma in her left breast and haemotological fea...

UNLABELLED Rosai-Dorfman Syndrome (RDD) is a rare, benign, self-limiting disorder which is characterized by the non-malignant proliferation of distinctive histiocytic cell within lymphatic system. RDD has been described as a dynamic entity in the spectrum of histiocytosis with non-Langerhans cell histiocytosis at one end and Langerhans cell histiocytosis at the other. The exact etiology of this...
