Tim, a 32 year old Canadian agricultural consultant, who has lived most of his life in Nigeria, presents to your clinic for travel immunization advice prior to undertaking a contract in Kenya. He has never taken antimalarial prophylaxis. His facial features were somewhat coarse, and there was obvious nasal crusting and bleeding. Nodules were present on his cheeks and ears, and both earlobes were quite large. Tim has a martial arts tattoo on the back of his right hand which was done as a teenager in Nigeria.
Upon questioning, he related that, two years previously, his hands began to swell and that weakness and wasting of his left hand followed. Several 'spots' appeared on his forearms and scaly skin on his left shin. He later developed a painless sore on the sole of his left foot.
Physical examination revealed keratitis present in both eyes. Nodules similar to those on the face were also present on his forearms and thighs, and scaly macules were distributed over the right tibia. The ulnar, popliteal and tibial nerves and the left radial nerve were clearly palpable. The patientâ€™s left hand was in an unusual claw-like posture at rest. Stocking and glove anaeasthesia was present distal to the mid-forearms, and distal to the mid-thighs. An ulcer was present on the sole of the left foot.
The patient had recently sustained an injury to his right hand - he caught his fingers closing the drawer of a filing cabinet. Apparently the drawer closed completely over two fingers but, while no bones were broken, Tim appears almost nonchalant about the injury.
