Extended Scalp Flaps for Extensive Soft Tissue Scalp Defects as a Day Surgery Procedure Under Local Anesthetic: A Single Centre Experience.

 Cutaneous malignancies are on the rise, associated with an increased number in scalp cancers that require wide local excision (WLE) to ensure clearance; the inelastic nature of the scalp poses a particular challenge when dealing with such large defects.  A series of 68 cases with large scalp defects following WLE for the clearance of squamous cell carcinoma, atypical fibroxanthoma, dermatofibrosarcoma protuberans, and melanoma skin cancers are presented. These cases were treated in one center under local anesthesia and underwent extended scalp flaps to close the resulting defect primarily without the use of skin grafts for the flap donor site on the scalp.

Mohs micrographic surgery for dermatofibrosarcoma protuberans (DFSP): a single-centre series of 76 patients treated by frozen-section Mohs micrographic surgery with a review of the literature.

Dermatofibrosarcoma protuberans (DFSP) is a rare low-grade sarcoma that typically presents with local invasion but rarely metastasises. Surgical excision remains the first-line treatment for DFSP. There are no randomised controlled or prospective studies comparing wide local excision (WLE) with Mohs micrographic surgery (MMS), but available evidence from the retrospective studies and case series available has consistently shown higher recurrence rates for standard surgery and WLE than for MMS.

Clinical value of immunohistochemically detected lymphovascular space invasion in early stage cervical carcinoma.

Background: This study investigates the clinical significance of lymphovascular space invasion (LVSI) as detected by hematoxylin and eosin (LVSI-H&E) and immunohistochemistry (LVSI-IHC) in early stage cervical carcinoma.

Methods: Single representative sections from 97 patients with early stage squamous cell cervical cancer were immunostained with pancytokeratin and CD31 endothelial cell marker antibodies. The H&E sections and their corresponding immunostained sections were reexamined to identify LVSI.
