Pilomatrix Carcinoma of the scalp. A case report and review of the literature

INTRODUCTION Pilomatrix Carcinoma (PC) is a rare and malignant dermo-hypodermic tumor. Only 11 cases were reported in patients younger than 18 years old and only 13 cases were reported on the scalp. CASE REPORT We report the case of a 15-year-old woman who underwent cyst excision on the vertex. Anatomopathology shed light trichilemmal cyst. Five months later, she presented a first local recurrence. The tumor was removed with wide margin. Anatomopathology shed light PC. No adjuvant therapy was performed. The patient presented a second recurrence 3 months later with a parietal bone and superior sagittal sinus invasion and a lung metastasis. She underwent a craniotomy and radiochemotherapy. A third local recurrence was detected 4 months later. Three more lines of chemotherapy were performed without success. DISCUSSION PC is a locally aggressive tumour, with a high rate of local recurrences and metastases. PC arises de novo or through malignant transformation of a pilomatrixoma. PC were observed frequently in the white male over 50 years old. The histological diagnosis is difficult to prove. Treatment consists of a wide surgical excision. Peritumoral margins are not codified. Because of most cases are on the face and neck, Mohs Micrographic Surgery seems to be a good modality to limit margins. Radiation therapy is an adjuvant treatment. Chemotherapy can be used in metastasis case. CONCLUSION PC is a rare malignant tumor with high rate of disease relapse. Histological diagnosis is difficult and treatment is not standardized. Surgical procedure with wide margins is recommended to avoid the large recurrence when the staging shows no metastasis.

Abdominoplasty and simultaneous laparoscopic ventral hernia repair. Clinical study about 45 patients.

INTRODUCTION Abdominoplasty procedures sometimes reveal the presence of ventral hernias (umbilical or trocar-site hernias). Our objective is then to deal with the excess abdominal skin and fat tissue at the same time as the ventral hernia. This can be done with a single surgical procedure combining abdominoplasty with umbilical transposition and laparoscopic ventral hernia repair (LVHR) with mesh. The main objective of our study is to assess the outcome of the combined procedure of abdominoplasty and LVHR with mesh, compared to abdominoplasty alone. MATERIALS AND METHODS A retrospective single-centre cohort study was conducted, including patients operated on with the combined method (ABDO-LVHR group) and patients who underwent abdominoplasty alone (ABDO group). We noted major and minor complications, with infection issues as our main concern. RESULTS We included 15 patients in the ABDO-LVHR group and 30 in the ABDO group. The results show no statistically significant difference for infectious complications in the ABDO-LVHR group compared to the ABDO group (20% vs 3.3%; P=0.100). There was no instance of complete umbilical necrosis. Other major and minor complications occurred at the rates typically described in the literature without difference between the two groups. CONCLUSION There was no significant difference between our two groups in terms of infectious complications. LVHR carried out at the same time as abdominoplasty with umbilical transposition is a positive combination of procedures. Further studies are necessary to confirm that the risk in terms of infectious complications is no higher than for abdominoplasty alone. LEVEL OF EVIDENCE III.

Zosteriform configuration of multiple eccrine spiradenomas of the scalp

BACKGROUND Eccrine spiradenoma (ES) is a benign adnexal tumor predominantly located in the head and neck regions. Multiple neoplasms located on the scalp have been reported but never with a zosteriform configuration on the first trigeminal area. CASE REPORT We describe an original case report of a 75-year-old Caucasian man presenting multiple subcutaneous blue and purple nodules disseminated on the first left trigeminal dermatome. All the nodules appeared gradually on a one-year period. Biopsy revealed a nodular adnexal tumor in the dermis without malignant eccrine spiradenoma (MES) transformation. The surgical procedure was performed in a manner to protect the galea aponeurotica in the upper half on the first left trigeminal area. The frontalis muscle was raised with the surgical specimen in the lower half of the first trigeminal area. A split-thickness skin graft was applied on the surgical defect. Histological examination revealed multilobular well-defined tumors located in the dermis. CONCLUSION The presence of multiple subcutaneous nodules in a trigeminal pattern should suggest a multiple localized zosteriform ES. The diagnosis is focused on clinical findings and the treatment is based on a large surgical excision. The histological examination is essential for not to fail a MES transformation.

Intraoperative instillation of ropivacaine during the placement of sub-muscular cosmetic breast implants: Is there a clinical benefit?

INTRODUCTION The sub-muscular placement of cosmetic breast implants leads to substantial pain due to the muscular distention. The aim of this study was to assess the efficiency of intraoperative ropivacaine instillation to reduce postoperative pain the day after surgery. MATERIAL AND METHODS We conducted a prospective, controlled, single-blinded study comparing the intraoperative instillation of 7.5mg of ropivacaine through Redon drains with the standard procedure in 72 patients undergoing sub-muscular cosmetic breast augmentation for the first time. RESULTS Pain at the awakening on postoperative day 1 was 4.8 on a simple numeric pain scale in the treatment group and 5.1 in the control group (P>0.05). On postoperative day 3, pain at awakening was 3.7 in both groups (P>0.05), and on postoperative day 5, pain was 2.8 in the treatment group and 2.7 in the control group (P>0.05). CONCLUSION Local instillation of ropivacaine in the implant pocket during surgery did not decrease postoperative pain on day 1, day 3 and day 5. From now on, we are able to tell to patients that the postoperative pain after sub-muscular cosmetic breast implants surgery is about 5/10 on postoperative day 1, 4/10 at day 3 and 3/10 at day 5.
