Wegener granulomatosis is a rare, chronic, multisystemic vasculitis affecting mainly the upper and lower respiratory tracts together with glomerulonephritis, but the disease may involve any other organ. Protracted superficial form is a rare variant of the disease. We report a case of protracted superficial Wegener granulomatosis in a 16-year-old boy in whom the disease started with recurrent digital ulcers at age 7 years. Later, he developed nodules and papules associated with upper airway involvement and ocular keratitis without lung or renal involvement. C-ANCA was positive. The patient was treated with oral prednisone. Similar cutaneous and mucosal lesions developed during two relapses of the disease without renal or respiratory involvement.

Background: Interspecific hybrids of rohu (Labeo rohita) and catla (Labeo catla) are common, especially in India due to constrained breeding. These hybrids must segregate from their wild parents as part of conservational strategies. This study intended to screen the hybrids from wild rohu and catla parents using both morphometric and molecular approaches.

Granulomatosis with polyangiitis, a form of necrotizing vasculitis can present as a limited variant with the involvement of a single organ system. The superficial protracted form can present as face and scalp ulceration for chronic periods of time. Diagnosis can be established histopathologically by examining the involvement of blood vessels.

: Hidradenitis suppurativa (HS) is a relapsing-remitting inflammatory disease characterized by the progression of asymptomatic nodules to deep-seated lesions and fistula formation that leads to suppuration and scarring. Optical coherence tomography angiography (OCTA) is a new non-invasive imaging technique that carefully analyzes retinal microvasculature networks with high-resolution imaging. Recent studies have demonstrated that retinal vessel density and retinal perfusion reflect systemic inflammatory responses.

Cranial bony projections ("headgear") have diverse forms and functions, such as defense, species recognition, mate selection, and thermoregulation. Most commonly, they are associated with the artiodactyl infraorder, Pecora. All pecoran headgear-antlers, horns, ossicones, and pronghorns-are osseous protrusions of the frontal or parietal bone with an integumentary covering, although there is taxonomic, developmental, and compositional variation.
