Case of leprosy mimicking preseptal cellulitis: a diagnostic dilemma.

A 36-year-old Asian man presented with swelling over the left frontal region involving the upper eyelids, with associated erythema and tenderness for 1 month duration. Clinically he was diagnosed as a case of preseptal cellulitis, however, the lesion did not improve on broad-spectrum systemic antibiotics. CT showed superficial soft tissue swelling in the forehead extending till the superior part of orbit. Histopathological assessment of the lesion revealed clusters of epithelioid cells with multinucleate giant cells in the dermis along with perivascular and periadnexal lymphocytic infiltrates, suggestive of leprosy. The patient was started on oral steroids with multidrug therapy, following which the patient showed early resolution of the lesion within 10 days of treatment. Leprosy is endemic in India, leprosy with reactional episodes mimics other inflammatory and infective etiologies making diagnosis difficult. Leprosy should be present in an ophthalmologist's diagnostic repertoire while dealing with periorbital swellings for early clinical diagnosis and favourable outcomes.

Leprosy type-I reaction episode mimicking facial cellulitis--the importance of early diagnosis.

Leprosy is an easily recognizable disease due to its dermato-neurological manifestations. It must be present in the physician's diagnostic repertoire, especially for those working in endemic areas. However, leprosy reaction is not always easily recognized by non-dermatologists, becoming one of the major problems in the management of patients with leprosy, as it presents clinical complications characterized by inflammatory process, accompanied by pain, malaise and sometimes the establishment or worsening of the patient's disabilities. We report the case of a patient with type-1 periorbital reaction admitted to the hospital, diagnosed and treated as facial cellulitis, whose late diagnosis may have contributed to the appearance or worsening of facial neuritis.

Facial tuberculoid leprosy: case report.

Leprosy is a chronic, infectious, systemic disease caused by Mycobacterium leprae and is classified as paucibacillary and multibacillary types. It is contagious and has an insidious onset. Clinical presentation is characterised by hypopigmented skin lesions with reduced sensation. Presence of acid-fast bacilli in tissue specimens is regarded as a gold standard for diagnosis. Treatment is based on multi-drug regimens. We report a case of borderline tuberculoid leprosy in a 31-year-old woman.

The potential role of magnetic resonance imaging in patients with Hansen's neuropathy of the feet: a preliminary communication.

A magnetic resonance imaging (MRI) protocol was performed in leprosy patients with a neuropathic foot and superficial ulcers and/or localized cellulitis but no clinical suspicion of osteomyelitis. The aim of the study was to determine if unsuspected osteomyelitis was present in this defined group of leprosy patients. A total of 15 neuropathic feet from 9 patients were included. Clinically and on MRI, the forefoot was predominantly affected. MRI findings of osteomyelitis were found in 4 feet. In feet with osteomyelitis, 3 had a superficial ulcer and 3 had clinical signs of localized cellulitis. A clinical diagnosis of cellulitis was confirmed on MRI in 2 feet.A striking discrepancy between clinical and MRI findings was found.This study shows that, compared with clinical evaluation, MRI is a sensitive method for the detection of unsuspected osteomyelitis in neuropathic feet with superficial ulcers and/or cellulitis. MRI findings in this group of patients may influence clinical decision making and may prevent further complications, because osteomyelitis requires more aggressive medical treatment. This preliminary communication should pave the wave for designed controlled studies so that patients with Hansen's neuropathy may get the best medical care.

MR imaging of neuropathic feet in leprosy patients with suspected osteomyelitis.

This study was undertaken to analyze MRI findings in leprosy patients with neuropathic feet, which are suspected of having osteomyelitis. As far as we know, there is no literature concerning osteomyelitis and MRI in neuropathic leprosy feet at present. Therefore, we have included MRI examination of 18 events of suspected osteomyelitis in 12 leprosy patients. All patients with long-standing neuropathic foot problems were clinically suspected of having osteomyelitis. All patients underwent the MRI protocol with the inclusion of Two Point Dixon Chemical Shift Imaging as a fat-suppression sequence. For the MRI evaluation, we used signs that are described in literature for detecting osteomyelitis in diabetic feet. The primary MRI signs were positive in 17 of 18 patients. The secondary MRI signs were positive in 100% of the patients. Our results show that MRI with the use of Two Point Dixon Chemical Shift Imaging is a promising diagnostic modality to detect osteomyelitis in the presence of neurosteoarthropathic changes in patients with leprosy. Whenever available, MRI could play an important role in detecting osteomyelitis in leprosy patients with long-standing neuropathic feet.
