Brain mucormycosis in a child with acute lymphoblastic leukemia.

This article reports a rare case of Brain Mucormycosis in a 12 year-old girl who presented with relapse Acute Lymphoblastic Leukemia (ALL). On the 12th day of chemotherapy, although there was no CNS symptoms, the second Lumbar Puncture (LP) revealedmthe CNS relapse which developed to Into brain abscess presenting with right side hemiparesis. The brain magnetic resonance imaging (MRI) and the brain biopsy revealed small, multifocal necrosis and acute inflammation with septal fungal hyphae branching, which was proven to be caued by Mucormycosis according to Polymerase Chain Reaction (PCR). The patient responded to treatment with intravenous liposomal Amohotericin B and Caspofungin after two months, suggesting that Brain Mucormycosis in ALL cases can be managed with sequential therapy by antifungals.

Visceral Leishmaniasis without Fever in an 11-Month-Old Infant: a Rare Clinical Feature of Kala-azar

Visceral leishmaniasis or kala-azar is an endemic parasitic disease in some parts of the world which is characterized by fever, splenomegaly, and pancytopenia in most of the cases. Herein we report an 11 month-old male infant with diagnosis of kala-azar who presented with pallor, hepatosplenomegaly, failure to gain weight, and no history of fever. Surprisingly, fever started after beginning of meglumine antimoniate treatment in this patient. As far as we are aware of, this is a rare presentation of visceral leishmaniasis. Therefore, clinicians especially in endemic areas are highly recommended to include kala-azar among differential diagnosis of unexplained anemia without fever to prevent misdiagnosis of this potentially fatal, but treatable condition.

Langerhans cells histiocytosis in one family.

Histiocytosis of Langerhans cells (class 1 histiocytosis) includes a range of clinical manifestations that have been described as bone eosinophilic granuloma, Hand-Schüller-Christian syndrome, and Letterer-Siwe diseases. This syndrome represents a spectrum of severity and prognosis of some underlying disorder which is usually sporadic. This report describes three cases in one family, who developed the disease a few years after their brother was found to be suffering from histiocytosis. All 3 patients had the same clinical manifestations: hyperthermia, eczematic rash, and swelling in skull, hand, and foot. X rays showed lytic areas in the skull and metacarp of fourth finger. Serology for EBV infection was negative. Infiltration of abnormal Langerhans cells histiocytes were demonstrated in bone biopsies. These patients were given chemotherapy. Case 1 (brother) died 1 year after chemotherapy, case 2 (girl) was given chemotherapy without success. She was given T-cell suppressor (cyclosporine), which induced remission, and case 3 was given chemotherapy, which was successful.
