1/20. Reddening of the upper central incisors associated with periapical granuloma in lepromatous leprosy.

    Four years after starting treatment for lepromatous leprosy in england a male Pakistani aged 26 was found to have red discoloration of the upper central incisor teeth. A radiograph suggested periapical abscess on the right with haziness in a corresponding area on the left. Right apicectomy was performed with removal of a solid mass attached to the apex, sections revealing a lepromatous infiltrate with acid-fast fragments of mycobacterium leprae in the cytoplasm of foamy macrophages. Clinical and archaeological evidence for the frequent involvement of these teeth in lepromatous leprosy is reviewed. The upper incisor area is relatively cool, a factor which may be of critical importance for the lodgement and multiplication of this bacillus, as it is in other body sites in lepromatous leprosy.

2/20. pathology of a lepromatous eye.

    Histopathological examination of an enucleated eye from a lepromatous leprosy patient showed the cornea, ciliary body, and part of the choroid to be infiltrated by macrophages filled with mycobacterium leprae. The walls of blood vessels in the sclera, ciliary body and the anterior choroid demonstrated the presence of M. leprae, giving credence to the blood-borne entry of M. leprae into the eye. Unlike the eyes of experimental animals infected with M. leprae, histopathological study of this eye from a lepromatous leprosy patient demonstrated that M. leprae, although demonstrable in the anterior choroid, could not be found in the posterior parts of the eye, substantiating the claim that leprosy does not affect the posterior parts of the eye directly.

3/20. acro-osteolysis prior to diagnosis of leprosy.

    lysis (bone resorption) has been observed in a heterogeneous group of congenital and acquired bone disorders. leprosy is the main cause of peripheral neuropathy leading to acro-osteolysis in endemic countries. Pure neuritic leprosy, a less common form of the disease, is difficult to diagnose. Two unrelated leprosy patients with acropathy whose disease began as pure neuritic are discussed.

4/20. Trochanteric hip fracture in an elderly patient with leprosy during osteoporosis treatment with risedronate and alfacalcidol.

    There is no well-established treatment for osteoporosis in male patients with leprosy, because no clinical trials have examined the efficacy of treatment on bone mineral density (BMD) or fracture incidence in patients with leprosy. In this study, we report a case of osteoporosis in a man with leprosy, treated by oral administration of risedronate and alfacalcidol. An 82-year-old man with leprosy presented to our hospital with chronic back pain, due to osteoporosis, in July 2002. To prevent the progression of osteoporosis, oral administration of risedronate and alfacalcidol was started for this patient. An increase in forearm BMD and a decrease in the level of urinary crosslinked N-telopeptides of type I collagen (NTx) were observed in January 2003. The patient suffered a trochanteric fracture of the proximal femur at the end of March 2003. Surgical treatment with a sliding-screw plate was performed 5 days after the injury. Complete bony union of the right proximal femur was confirmed by radiography in July 2003. The above findings suggested that the treatment with risedronate and alfacalcidol contributed to the increase in BMD; however, the treatment did not prevent fracture due to osteoporosis in this male patient with leprosy.

5/20. Radionuclide bone-scan abnormalities in leprosy: case reports.

    Radionuclide bone scans were performed on two patients with leprosy. The resulting scan patterns simulated hypertrophic osteoarthropathy and diffuse arthritis, findings entirely consistent with the primary disease process.

6/20. The results of arthrodesis of the ankle for leprotic neuroarthropathy.

    Twenty-four patients who had arthrodesis of one or both ankles for leprotic neuroarthropathy were followed for an average of nine years and five months. At operation, after the removal of cartilage, joint debris, and sclerotic bone, the ankle joint was transfixed with a Kuntscher intramedullary nail, and staples or Kirschner wires were used to control rotation. Fusion of bone was obtained in nineteen (73 per cent) of the twenty-six ankles. Failure to obtain fusion was due to postoperative infection in four patients, deficiency of the site of arthrodesis in one patient, and refracture through the site of fusion in two patients. When arthrodesis was successful, additional neuroarthropathic destruction of the mid-tarsal joint was halted, and the preoperative clinical symptoms of dull pain, local warmth, swelling, and instability were relieved.

7/20. Severe polyneuropathy in tangier disease mimicking syringomyelia or leprosy. Clinical, biochemical, electrophysiological, and morphological evaluation, including electron microscopy of nerve, muscle, and skin biopsies.

    Polyneuropathy in tangier disease can be divided into three clinical types. The most severe form (type III) with a syringomyelia-like syndrome has been described in three cases only. Here, a fourth case of this type is presented. Because of unusual trophic disturbances even leprosy was suspected. Electrodiagnostic findings, including evoked cerebral potentials in this case, were suggestive of a generalized neuropathy with some degree of primary or secondary demyelination and implied possible impairment of central structures. sural nerve biopsy, including electron microscopy and quantitative analysis, revealed a predominant reduction of smaller myelinated and unmyelinated fibres. The main morphological feature was the abundance of abnormal non-membrane-bound vacuoles in schwann cells, mostly of the unmyelinated type, and in some endoneurial fibroblasts, macrophages and perineurial cells. There was no inverse relationship between lipid vacuoles and axons in Schwann cell complexes as suspected by others. An excess of endoneurial collagen as well as an increased fascicular area were obvious. In five skin biopsy specimens of different regions typical vacuoles were noted in schwann cells, histiocytes, nevus cells, and rarely in perineurial cells.

8/20. Primary visceral virchowian (lepromatous) hanseniasis.

    A case of primary visceral virchowian hanseniasis is presented. The onset and symptoms of the disease made one think that it was a lymphoma because of the severe enlargement of the liver, spleen, and lymph nodes. Biopsies of the liver, lymph nodes, and bone marrow revealed virchowian infiltration with acid-fast bacilli and globi. The skin was free of lesions and negative to bacilli, and there were no neural symptoms.

9/20. Histoid leprosy in singapore.

    Histoid leprosy is a rare variant of lepromatous leprosy. This is the first documented case of histoid leprosy in singapore. The patient was diagnosed as borderline leprosy in 1973, remained untreated and progressed to lepromatous leprosy. The characteristic histoid lesions were firm pruriginous nodules on the dorsum of his feet. The histology showed a pseudocapsulated tumour with fibroblasts and histiocytes filled with lepra bacilli. Electron microscopy showed fibroblasts, macrophages with bacilli and plasmacytoid cells with active endoplasmic reticulum. He was found to be dapsone-resistant and the lesions cleared with clorphazimine. Immunological defects were not detected.

10/20. erythema nodosum leprosum reaction of leprosy causing the double stripe sign on bone scan. Case report.

    leprosy is a disease that is widely distributed in underdeveloped tropical regions, with cases also occurring in the united states. The bone scan findings in a patient with leprosy who had developed a reactional state of the disease, erythema nodosum leprosum, are presented. His scan showed bilaterally symmetrical double stripe signs involving the distal tibias, similar to those seen in hypertrophic osteoarthropathy. physicians should be aware that this reactive phase of leprosy can also produce the double stripe sign.
