Subcutaneous fat necrosis of the newborn with eosinophilic granules.

Subcutaneous fat necrosis (SFN) of the newborn is a variant of lobular panniculitis characterized by focal areas of fat necrosis and a granulomatous infiltrate composed of lymphocytes, histiocytes and multinucleated giant cells. Lipocytes and histiocytes contain needle-shaped clefts in a radial arrangement. Needle-shaped clefts may also be seen within the cytoplasm of multinucleated giant cells.

Thrombogenic vasculopathy with diffuse neutrophilic inflammation: a histologic manifestation of a tick bite.

We describe 5 cases of tick bite reactions with dermal necrosis and sparse interstitial to dense diffuse dermal neutrophilic infiltrates associated with thrombogenic vasculopathy. Tick bite reactions classically consist of moderately dense perivascular infiltrates composed of an admixture of inflammatory cells. Each of our patients had embedded tick parts, with interesting histologic features.

Advancement flap for the reconstruction of nasal ala and lateral nasal tip defects.

Repair of nasal ala and lateral nasal tip defects provide unique reconstructive challenges. This article describes a one-staged advancement flap for repair of such defects. The flap may be medially-based, laterally-based, or bilaterally-based.

Novel technique for use of cyanoacrylate in Mohs surgery.

Background: Many Mohs procedures involve the handling and manipulating of thin, fragile skin tissue, particularly eyelid skin. After excision of such tissue, proper handling of the tissue becomes critical for tissue orientation and histologic processing.

Objective: The authors present a novel way to handle thin, friable tissue after excision in Mohs surgery with the direct application of cyanoacrylate onto freshly excised tissue.
