When dealing with giant lipomas, liposarcomas should always be included in the differential diagnosis.

Despite the abundance of epidemiologic studies concerning hand injuries, there is no study that emphasizes the significance of the initial laceration size. The aim of this study is to investigate the incidence of tendon, nerve, and artery injuries that may result from small, penetrating lacerations of the hand and forearm. A total of 226 patients with small lacerations were included in the study. Glass (68.7%) and knife (31.3%) lacerations were the only etiological factors. One hundred thirty-four patients (59.3%) had at least 1 deep-structure injury. One hundred twenty-four patients (92.5%) had at least 1 tendon, 25 patients (18.7%) had at least 1 nerve, and 20 patients (14.9%) had at least 1 artery injury. Extensor tendons were more commonly injured (61.3%). Combination injuries were found in 20 (14.9%) patients. The most-encountered combination was the injury of all 3 structures. Small laceration injuries of the upper extremity have the potential to conceal an underlying deep injury.

Multiple occurrences of pilomatrixoma are rare. Although it has been known as a benign lesion, there are reports of some tumors that have histopathologic features of malignancy. A case of a 68-year-old Caucasian women with multiple pilomatrixoma is presented. She was operated on to remove three other pilomatrixomas on the arms 3 years after the initial excision from the face. Two years after excision of the lesions on the arms, no recurrences were evident.
