###Major tuberculoid (plaques, annular lesion etc.)
(a) Indeterminate leprosy; (b) tuberculoid leprosy; (c) lepromatous leprosy; (d) Ziehl-Neelsen staining.
Histopathological results after HE staining of all three cases showed tuberculoid granulomata with giant cells (Figure 2(a)), numerous lymphocytes, histiocytes and eosinophilic cells (Figure 2(b)), an amorphous eosinophilic material also known as the "Splendore-Hoeppli phenomenon" (Figure 2(c)), and 10 [micro]m diameter septate hyphal fragments (Figure 2(b)), confirmed also by the Gomori-Grocott staining (Figure 2(d)).
Paucibacillary forms (bacilli being sparse) include TB verrucosa cutis, tuberculoid, and lupus vulgaris [17,18].
Borderline tuberculoid leprosy masquerading as granuloma annulare: a clinical and histological pitfall.
It includes tuberculoid (TT), borderline tuberculoid (BT), indeterminate (I) and pure neuritic (PN) forms, in which the skin smear is negative and/or the number of skin lesions is 1-5.
The clinical spectrum proposed by Ridley and Jopling (R&J) consists of two poles: tuberculoid (TT) and lepromatous (LL), and three intermediate forms: borderline-tuberculoid (BT), borderline-borderline (BB), and borderline-lepromatous (BL).
Patients suffering from leprosy exhibit a wide spectrum of presentation ranging from tuberculoid to the lepromatous pole, with the immunologically unstable borderline forms in-between, depending upon the immune status of the individual [2, 3].
Of the 11 cases of leprosy, 7 cases (63.63%) were of lepromatous leprosy, 2 cases each were of histoid leprosy, and tuberculoid leprosy.
Significant differences (p < 0.05) were found between Group I and the other groups for tuberculoid clinical presentation of leprosy.
