leprosy masquerading as granuloma annulare: a clinical and histological pitfall.
Thus, mast cells can be used as an important indicator of the patient immunity in leprosy; as such these are found more in lepromatous than tuberculoid
leprosy presents with macules or plaques.
The cellular immunity in leprosy tuberculoid
type is still good, on the contrary, there is decreased cellular immunity in leprosy lepromatous type.
The slides were then examined by a histopathologist and the reports were interpreted as tuberculoid
, borderline tuberculoid
, mid borderline, borderline lepromatous and lepromatous leprosy.
Additionally, in tuberculoid
patients, in which bacilli are rare or nonexistent, there is always a limitation in using bacilloscopy as an auxiliary exam, once negative results do not rule out the disease.
observed most commonly encountered type of leprosy to be borderline tuberculoid
leprosy was the most frequent morphologic type, seen in 56.
Liver involvement in leprosy is often subclinical, yet more than 60% of patients with lepromatous leprosy have hepatic involvement, and approximately 20% of patients with tuberculoid
leprosy do as well.
leprosy was the most frequently found subtype of leprosy (n=81; 43.
Histopathological examination of the biopsy samples showed normal epidermis and caseating tuberculoid
granulomas containing epithelioid histiocytes and Langhans giant cells in the papillary dermis (Fig.
granulomatous infiltrate is most helpful, but some patients may instead have a lymphohistiocytic infiltrate, palisading or sarcoidal granulomas, a mixed inflammatory infiltrate, or other nonspecific findings.
