This report describes two incidental findings of aberrant branches of the radial digital nerves in the middle finger of a 52-year-old man who cut himself with a grinding machine, and in the index finger of a 45-year-old female who sustained a flexor sheath infection following a dog bite. In both patients, two equally sized radial digital nerves were found and both nerves originated from one common digital nerve.

AIM: To identify and review cases of false negative needle core biopsy (NCB) in the preoperative investigation of radial scar/complex sclerosing lesion (RS/CSL) lesions - that is, benign NCB from RS/CSL which contained malignancy on excision. METHODS AND RESULTS: A total of 11 false negative NCB in RS/CSL lesions from 281 (3.9%) were identified (6 cases: B1, 2 cases: B2 and 3 cases: B3). In 6 of 11 cases a radial scar or stromal sclerosis was seen in NCB. Localisation biopsy showed duct carcinoma in situ in six cases, duct carcinoma in situ with invasive carcinoma in three and invasive carcinoma in two. In all 11 cases, needle tracks were identified as missing the malignant epithelium by a mean of 5 mm (median:4 mm; range:1-20 mm). In 9 of 11 cases, the malignancy was missed by <6 mm. CONCLUSIONS: Despite evidence of accurate targeting of lesions, the use of NCB instead of fine needle aspiration cytology has not eliminated the problem of false negative biopsy in RS/CSL, and excision is recommended.
