Facial skin wounds are common problems seen and treated by emergency centers around the world. Among all wounds, cat and dog bites are frequently seen. Human bite injuries are both deceptive and difficult in their presentation and management. The injuries have a disfiguration effect with possible psychological impact on the patient. The aim of this paper is to compare experience with human bites of the face in our surgical unit, with other similar trials in term of reasons for the circumstances of injuries, age, and sex of the patients, site of injury, pan-time between consultation and treatment, incidence of infection and surgical management. Data in terms of age, gender distribution, circumstances of injury, location of injuries, evolution of surgical management and complications were recorded. We report here a series of 10 cases of human bite wounds to the face, admitted to our department, and treated with different reconstruction procedures.

Background the solitary plasmacytomas entities characterized by the neoplastic proliferation of a single clone of plasma cells, typically producing a monoclonal immunoglobulin. It represents less than 5% of plasma cell dyscrasias. The most common sites of solitary plasmacytomas are long bones. The jaws location remains extremely rare, only 4.4% of solitary plasmacytomas of bone occur in the mandible, the diagnosis is based on the biopsy evidence of plasma cell proliferation and absence of evidence of involvement of other bones. Case presentation The authors report the case of a healthy 49-year-old man with no general history, presented with a painless slow-growing lesion of the left jaw that had persisted and increased in size for one month. Clinical examination revealed a large lesion 4 × 4 cm with irregular borders of the retro-molar area on the left jaw, infiltrated into underlying tissue, with sensory disturbances and facial asymmetry. Conclusion Treatment methods of plasmacytomas of the jaw include local surgery (curettage of the lesion), local irradiation, systemic chemotherapy, or a combining therapy. Early diagnosis and treatment are crucial for better resolution of the disease.

Syringocystadenoma papilliferum is a rare benign adnexal tumour of the sweat glands. It is considered an infantile tumour since it preferentially affects the newborn in 50% of cases and the child before puberty in 15–30% of cases. And its preferential location is the head and neck, but rare in the face. And the first line treatment remains surgery. We report here a case of Syringocystadenoma papilliferum in a nasal location in a 70 year old subject with a history of pemphigus vulgaris, treated by surgical excision, whose postoperative course was aggravated by Koebner phenomenon.
