New World cutaneous leishmaniasis imported into Australia.

A case of cutaneous leishmaniasis in a traveller from Belize, Central America is reported. Leishmaniasis presents rarely in Australia and delays in diagnosis and treatment often occur. A high index of suspicion in a patient who has returned from an endemic region is required. Subsequent confirmation of a diagnosis of cutaneous leishmaniasis is best achieved by demonstration of the organism on skin biopsy, aspiration or smear. The histology is variable and depends on geographic, parasite species and host factors. Speciation of New World disease as either Leishmania braziliensis or Leishmania mexicana is important to determine the risk of later development of mucosal disease, which normally only occurs with L. braziliensis infection, and for optimal treatment. Several different modes of treatment have been suggested, but antimonials, such as sodium stibogluconate, remain the treatment of choice in New World cutaneous leishmaniasis.

Chromoblastomycosis: a retrospective study of six cases at the Royal Darwin Hospital from 1989 to 1994.

Chromoblastomycosis, a localized chronic cutaneous and subcutaneous infection of the skin caused by pigmented fungi, is most common in the world's tropical and subtropical zones. The condition rarely occurs in Australia. We present 6 cases of chromoblastomycosis seen at the Royal Darwin Hospital, Northern Territory, from 1989 to 1994 and affecting predominantly male Caucasians ranging from 38 to 71 yrs of age. Clinically the lesions were verrucous or nodular. They mimicked basal or squamous cell carcinoma, nevi or solar keratoses. Histopathologic findings were nonspecific. The only pathognomonic finding was the presence of brown spores or sclerotic bodies within granulomata or within microabscesses in the skin.

Cementifying fibroma of the maxillary antrum.

A 26 yr old Caucasian, previously healthy, noticed a painless swelling of the left palate of 2 mths duration. On examination, a left maxillary swelling was noted with extension into the cheek. The mass was compressible. The CT scan revealed a large expansive tumor. Histological diagnosis of the enucleated lesion was cementifying fibroma. We describe a case of cementifying fibroma of the maxilla, an unusual location for this tumor.

A unilateral mesenchymal disorder of the head.

A hitherto undescribed group of lesions consisting of cystic bony lesions, exostosis, fibromatous lesion, unilateral tonsillar hypertrophy, epidermoid cyst (cholesteatoma) and hyperplasia of the mandible confined to the left side of the face is reported. The case may represent a variant of the Proteus syndrome.

Primary malignant fibrous histiocytoma of the stomach: (a case report).

A case of primary malignant fibrous histiocytoma (MFH) of the stomach is reported. The patient was a 51-year-old man who had a laparotomy for a malignant gastric tumour diagnosed by radiological studies and endoscopic examination. An inoperable gastric malignancy was found at operation. Histopathological studies of tissue biopsied at surgery showed characteristic light microscopic findings and strong positivity for alpha-1-antitrypsin by immunoperoxidase technique indicating the diagnosis of malignant fibrous histiocytoma. The absence of any other soft tissue or retroperitoneal tumour strongly indicated the stomach is the primary site.

Pulmonary aspergilloma. Case reports from Malaysia.

Pulmonary aspergilloma is by no means uncommon in Malaysia. The lack of documentation of its occurrence in Malaysia, is mainly due to the lack of clinical awareness, and the absence of facilities for the proper diagnosis of the infection.
