Schwannoma of infratemporal fossa in a young child.

Schwannomas in children are rare. A nine-year-old boy presented with swelling right side of face and proptosis for 4 months. CT scan showed a heterogenous mass in the right infratemporal fossa and extending to the posterior ethmoid. There was erosion of the bony walls of the infratemporal fossa. A biopsy through the sublabial approach was reported as schwannoma. The tumour was approached by Weber-Ferguson approach and excised in toto with complete relief of symptoms.

Drug-induced acute pancreatitis. A critical review.

Acute pancreatitis has a high morbidity and significant mortality. Among its many causes ethanol is pre-eminent, but many other drugs have also been incriminated. This article begins with a definition of the mechanisms, pathogenesis and clinical features of acute pancreatitis; it then critically reviews the evidence for drugs, excluding ethanol, as being causative. The drugs which have been implicated are considered under 3 headings: definite associations, probable associations and unlikely associations. A brief outline of possible treatment, strategies and prognosis associated with acute pancreatitis concludes the article.

Familial hemophagocytic lymphohistiocytosis: an autopsy study.

We describe four classical cases of familial hemophagocytic lymphohistiocytosis (FHL), a macrophage-related, autosomal recessive fatal disorder. Parental consanguinity was present in three cases. All patients presented with fever, neurological involvement of varying degrees, hepatosplenomegaly, cytopenias, deranged liver function tests, and coagulogram, hypofibrinogenemia (three cases), and hyperlipidemia (one case). An antemortem diagnosis could not be made, although it was suspected in one case. Necropsy (done in three cases and postmortem liver biopsy in one case) revealed classical features of FHL. Florid lymphohistiocytic infiltrate exhibiting hemophagocytosis was seen in the bone marrow, liver, spleen, lymph nodes and brain (examined in two case). In addition to this, focal infiltrates were seen in the kidneys, lung, pancreas, testes, adrenals, and skin. Marked lymphoid depletion was seen in one case in the lymph nodes and spleen.

Craniospinal enterogenous cyst: MR findings.

An enterogenous cyst of the craniocervical region producing anterior medullary compression is reported. The patient presented with quadriparesis with greater involvement of the upper limbs. Computed tomography showed a high attenuation intradural extramedullary mass located anteriorly. Magnetic resonance imaging demonstrated a high intensity mass extending from the pontomedullary junction to the second cervical vertebra, flattening the medulla and upper cervical cord. Complete recovery ensued following total excision of the cyst.

Mucormycosis in patients with renal failure.

Nine fatal cases of systemic mucormycosis observed in association with renal failure are described. Four patients were hospitalized for chronic renal failure as a consequence of chronic glomerulonephritis, myeloma kidney, chronic pyelonephritis, and polycystic kidney disease, respectively; and five patients presented with acute renal failure. The underlying causes in three of these five patients were gentamycin nephrotoxicity, acute gastroenteritis, and allograft rejection, respectively, and in the remaining two, acute renal failure was the result of extensive renal vascular and parenchymal invasion by mucor hyphae. Tissue invasion with mucormycosis was documented during life in two patients and at autopsy in seven patients. The infection was disseminated in five patients, and isolated pulmonary and rhinocerebral involvement occurred in two patients each. Our observations have shown that patients with renal failure are prone to develop mucormycosis, which carries a grave prognosis if therapy is not instituted in time.

Atypical cytologic features of medullary carcinoma of the thyroid. A review of 12 cases.

A total of 12 cases of medullary carcinoma of the thyroid were reviewed with regard to atypical cytologic features. They included clusters of cells with a follicular arrangement, papillary fronds, spindle-shaped cells, pleomorphic nuclei, nucleoli and intranuclear inclusions. Congo red staining on selected destained smears was positive for amyloid in three cases. Histology was also available in 12 cases. Two cases were incorrectly diagnosed as papillary carcinoma and one as follicular carcinoma on cytology. There were no false-positive diagnoses.
