TitleFoot with fungal mycetoma
DescriptionFoot with fungal mycetoma
The preparation is a right foot in parasagittal section, showing the white variety of mycetoma. This is caused by a fungus (eumycetoma), which is less common in Asia than bacterial mysectoma (actinomycetoma). The agent enters the skin and caused hard painless masses under the skin, which can develop into sores and destroy underlying bone.
From a Hindu aged 40 years, the affection of whose right foot had commenced fourteen years previously by a small movable tumour over the metatarsophalangeal joint of the right hallux. The tumour gradually enlarged, ulcerated on its surface, and when squeezed discharged sanguineous pus and reddish small oval granules. Similar swellings appeared until the whole foot was involved. The tumours caused severe pain which was relieved by incision.
On the dorsum, especially towards the toes, and on the skin of the medial surface a number of rounded flattened masses project. Elsewhere and on the plantar aspect small rounded ulcers form sinuses. On section there is cutaneous overgrowth, much fibrosis, and many irregular cavities the largest of which extends from the talus and calcaneum to the meta-tarsophalangeal articulations and contains the remains of the tarsal and metatarsal bones much destroyed by decalcification. The organism is descomyces madurae and the fungus forms channels and cysts and leads to destruction of the bones. The characteristic granules are yellowish-white.
