Livedo reticularis was also detected on the palmar surfaces of the index fingers of both hands, and erythematous linear plaques (flagellate erythema) were noticed on both inner thighs (Fig. 1).
a High-resolution CT of the chest showed multifocal areas of ground-glass attenuation. b A skin biopsy specimen from the right 3rd knuckle showed focal interface changes with sparse inflammatory cell infiltrate (hematoxylin and eosin staining, original magnification x100).

A high-resolution CT scan of the chest revealed multifocal areas of ground glass attenuation and alveolar opacity throughout the lung parenchyma and predominately at the peripheral and peribronchiolar regions (Fig. 2). Histopathological findings from the right 3rd knuckle revealed interface changes with sparse inflammatory cell infiltrate (Fig. 2).
