Introduction: Trichilemmal cysts (TCs) are common skin lesions that occur in hairy areas. A TC involving a fingertip has not been previously described in the literature. We herein report a case of a TC occupying a fingertip region.Case presentation: A 43-year-old woman presented with a 1:5 Â 1:5 cm nodular lesion on the third fingertip. The lesion was completely excised, and histopathological examination revealed a TC.Conclusion: TCs may involve atypical locations, such as fingertips, where there are no hair follicles. After surgical excision, a careful histopathological examination should be performed to differentiate TCs from proliferating pilar tumors.

Soft-tissue defects of the pretibial region constitute a major reconstructive challenge because of the insufficiency of the local tissues. In such cases, a long cross-leg flap may be an alternative option. This study presents a case with an atonic wound in the pretibial region caused by a previous traffic accident, which had received cross-leg flap repair following the excision.

The deltoid free flap is a thin, reliable flap that is easily dissected from the posterolateral arm. It has large-caliber vessels and is capable of sensory reinnervation to portions of the flap above the deltoid/triceps groove through the lateral brachial cutaneous nerve. There is little sensory return to the large vascular territory, which can be extended inferiorly below the deltoid triceps groove. The donor site can be closed primarily or skin grafted and when large may be objectionable to some patients. The flap is an excellent choice for extremity soft-tissue reconstruction on the plantar or palmar surfaces. Because of its excellent color-matching and texture-matching characteristics, it has recently been widely used for the reconstruction of soft-tissue defects during oral and maxillofacial surgery.
