Pyrexia of unknown origin: a rare presentation of primary ovarian lymphoma

It is very rare to have a lymphomatous involvement of ovary. Malignant lymphoma of ovary is a well-known late manifestation of disseminated nodal disease. Primary ovarian lymphoma with ovarian mass as an initial manifestation is a rare entity and may have varied presentations which can cause confusion to the physician and cause delay in diagnosis. Study presents a case of non-Hodgkin’s lymphoma where the initial presentation was fever with weight loss, and was evaluated as pyrexia of unknown origin. When no other cause of fever was identified PET-CT was done showing metabolically active uterine mass with no lymphadenopathy. Exploratory laparotomy was planned followed by hysterectomy with bilateral salpingo ophorectomy with omentectomy. Ovarian malignancy was detected intraoperatively, which was diagnosed as diffuse large B cell lymphoma, NHL double expresser phenotype on histopathology and IHC. Patient was started on chemotherapy and is doing fine.

Extramedullary hematopoiesis in ovary: a rare presentation of CML

Extramedullary hematopoiesis (EMH) is a rare phenomenon, and represents infiltration and proliferation of myeloid, erythroid, and megakaryocytic cells in non-bone marrow sites. Extramedullary hematopoiesis (EMH) is normal during fetal life, but after birth, the presence of EMH is considered to be abnormal.  EMH has been associated with CML (chronic myeloid leukaemia). Lymph node is the most common site of involvement, other sites being the abdomen (liver, spleen) and thorax (bone, mediastinum) but very rarely in the gynecological tract. Here authors report a case of a 20-year young female, a known case of CML who presented with abdominal pain with hemoperitonium, with negative urine pregnancy test. Initially hemorrhagic corpus luteal cyst was thought to be the cause of hemoperitonium and patient was taken for surgery wherein histopathology confirmed the diagnosis of extra medullary hematopoiesis of ovary. Women with CML when presents with hemoperitoneum, extramedullary hematopoiesis should be a differential diagnosis apart from rupture ectopic and other causes of spontaneous hemoperitoneum.  Patient was started on imatinib after diagnosis and is doing well.
