We report a case of a 50-year old female presenting with a giant tumor on the volar aspect of the third finger of the left hand, a thorough clinical and paraclinical evaluation followed by surgical resection resulted in a benign lipoma with an uneventful postoperative course. We present this case due to its rare location and repercussion in the decision making process when other more common similar pathologies with varying prognosis are conceived.

Introduction: Mallet injuries are common and usually treated conservatively. Various systematic reviews have found a lack of evidence regarding the best management, and it is still unclear. Objective: To evaluate the treatment efficacy of Stack Splinting compared to a Kirschner wire immobilization of acute closed mallet finger Doyle I. Methods: From March 2019 to February 2020, 41 patients with acute close mallet finger Doyle I were treated; 19 patients were treated with Kirschner wire and 22 with Stack splinting for a mean of 6 weeks. The average patient age at the time of the injury was 43 years. Results: Twenty-eight males and 13 females were in this study. Among them, 17 patients were injured in the little finger, 15 in the middle finger, and 9 in the ring finger. Twenty-seven of injuries suffered an aggression, 11 from falling, and 3 from sports injuries. All the fingers had typical mallet malformation. Seventeen patients treated with Kirschner wire completed the treatment with full recovery, only 7 patients treated with Stack splint completed the treatment and 15 treated with Stack splint had relapse on mallet injury. Conclusion: Kirschner wire treatment is a simple procedure, and proves in this study that has better results in patients with acute closed mallet finger Doyle I compared to Stack splint.

Osteoid osteomas are benign skeletal tumors; more than half of the lesions occur in lower extremity long bones, with very few cases reported in metacarpal bones. We presented the case of a patient at the plastic surgery department of a regional hospital, who presented with a tender tumor in the left hand over the past 2 years.

Background: Animal bites are a common cause of primary care and emergency department attention worldwide. However, the incidence of this pathology among Mexican population is not well known. Plastic surgeons are at the forefront of initial attention and final outcome of these destructive wounds in our country. The aim of this study was to describe the epidemiology of animal bites over a 5 year period at a level II general hospital in Mexico city. Objective of current study was to determine the incidence of animal bites in hospital “Rubén Leñero” in Mexico city over a 5-year periodMethods: Retrospective study; records of emergency room of all adult patients who sustained animal bites between January 2016 to December 2020 were collected. Details about age, gender, and location of the injuries were recorded and analyzed.Results: From a total of 277 cases, 273 were dog bites (98.56%) and 4 cat bites (1.44%), 173 males (62.45%) and 104 females (37.55%) were affected. The two most injured places in the human body were the hand with 98 cases (35.37%), followed by the lips in 45 cases (16.25%).Conclusions: Animal bites are a frequent injury in the primary care unit, representing a health issue in our country. Proper patient evaluation and treatments are essential to prevent further complications and subsequent infections. Further investigation will be required to establish risk factors for this pathology.
