Currently the hematoxylin and eosin staining procedure is the most popular among Mohs surgeons for histology. However, safranin O, a cheaper and relatively safer stain which is predominantly used for plant histology, should be considered as it offers similar or improved accuracy in the diagnosis of frozen sections of basal and squamous cell carcinomas.
A case of actinic comedonal plaque is reported. We comment on the case as well as describe the skin surface microscopic features.
BACKGROUND: Defects of the distal nose are particularly challenging to reconstruct because of this area's unique texture, lack of elasticity, and possible distortion of the alar rim. The bilobed flap has been criticized for having a high incidence of "trapdooring," flap necrosis, dog ears, and prominent suture lines. METHODS: Patients who underwent bilobed flap repairs of the distal nose (n = 171) were reviewed for complications and cosmetic results. The modifications from the traditional design include minimizing the angle of transposition between lobes, thinning of the flap, basing the pedicle on the lateral aspect of the nose, and creating the lobes of the flap to be of equal diameter to the defect. RESULTS: There was a 3% incidence of infection, 7% incidence of partial flap necrosis, and 5% incidence of "trapdooring" and contour distortion. Color match and contour were excellent for all other patients. CONCLUSIONS: The modified bilobed flap is an excellent choice for reconstruction of defects of the lower nose because of the good skin match and low incidence of complications.
