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(More)
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(More)
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(More)
Pigmentation featured millions of years ago and perhaps began with an amoeba frightening off a predator with some agent such as dopamine to prevent its attachment for phagocytosis by an enemy. This paper suggests that the environmental forces of grip and stick deserve greater emphasis and that mechanical forces involved in grip and stick or release from(More)

This paper suggests that the environmental forces of grip and stick, rather than pure chemical influences, deserve greater emphasis, and that the influence of the(More)
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(More)
Biomedicine has not provided a complete explanation with fully effective therapies for disorders of pigmentation. Biomedicine emphasizes the role of melanocyte for protection from UV rays and as a determinant of skin colour. These important properties acquired a genetic basis much later than other functions, many relating to cell contact as in the(More)
