A solitary cystic lesion in the abdominal wall is generally benign, such as an omental cyst, mesenteric cyst, enteric duplication cyst, cystic mesothelioma, or skin appendage tumor. Furthermore, most malignancies in the urachal remnant are intraperitoneal lesions, and generally develop on the anterior aspect of the bladder dome. Moreover, most urachal glandular malignant neoplasms are the mucinous cystic type. We report a cystic urachal adenocarcinoma that presented as an abdominal wall cystic lesion. A 42-year-old woman was admitted to Kangwon National University Hospital for a 5-cm palpable abdominal wall mass. Conservative surgical excision was performed with subsequent histological and immunohistochemical evaluations, but only a few non-mucinous invasive glands and finger-like growths were noted. During a 2-year period, the tumor recurred several times along the urachal tract and metastasized to the regional lymph nodes. Despite receiving chemotherapy, the patient died 2 years after the first surgery.

We report the case of a 25-year-old man with a maxillary ghost cell odontogenic carcinoma (GCOC). The patient presented to the maxillofacial and head and neck surgery clinic with a growing lump in the left maxilla. Initial workup with CT revealed a cystic lesion in the left upper jaw with associated bone erosion and an enhancing soft-tissue component. Enucleation showed a GCOC associated with a calcifying odontogenic cyst. After the diagnosis was obtained, the patient underwent widening of the first surgical resection. GCOCs are rare odontogenic neoplasms with unspecific clinical and imaging presentation, whose definitive characterisation is based on pathology. Current treatment approaches mainly involve surgical excision, but the prognosis is highly unpredictable due to intertumoral heterogeneity. As tumour recurrences occur in 73% of cases, radical surgery with negative margins is highly recommended. Therefore, it is essential to recognise this entity to offer patients adequate management.

Long Term Survey

The urachus establishes a connection between the dome of the bladder and the umbilicus throughout fetal life. If the urachus does not close completely, malignancy is a potential complication. The primary treatment for malignant urachal tumor is surgical excision. A 61-year-old male patient diagnosed with urachal carcinoma had undergone partial cystectomy 25 years previously. Twenty years later, local recurrence was treated with another partial cystectomy without umbilical remnant excision. Recurrence at the umbilical site was excised 2 years later, but intraperitoneal invasion had occurred, and the patient underwent a total colectomy at that time. Local disease and disseminated metastases in the thorax and intra- and extraperitoneal areas were noted upon admission to our hospital. Urachal carcinomas are usually aggressive tumors, and surgical treatment should include partial or radical cystectomy and excision of the urachus and umbilicus, to prevent local recurrence and distant metastasis.

Benign Schwannoma

Summary Background Schwannoma is a benign tumor arising from Schwann cells of the peripheral nerves. It is often asymptomatic and can develop in the retroperitoneum, mediastinum, head and neck region, and upper and lower extremities. Schwannoma of the abdominal wall is extremely rare, but differential diagnosis with malignant neoplasms is important to reduce the risk of undertreatment. Methods A narrative review of abdominal wall schwannoma was performed using PubMed, EMBASE, and Web of Science database and the search terms “schwannoma”, “neurinoma”, “neurilemmoma”, “soft tissue tumors”, “neurogenic tumor”, “rectus abdominis mass”, “abdominal wall”. In addition, the hospital charts were reviewed to report the personal experience. Results Only 9 single case-reports of benign schwannoma of the abdominal wall were found in the English medical literature over the past decade. None of the patients received preoperative biopsy and all were resected with clear margins. In addition to the literature review, we report the case of a 58-year-old man referred for a palpable mass in the left upper abdominal quadrant. Ultrasonography and magnetic resonance imaging revealed a solid and well-encapsulated mass inside the left rectus abdominis muscle. A core biopsy of the lesion provided the diagnosis of cellular schwannoma and this was confirmed by histopathologic examination of the surgical specimen. Conclusions Benign schwannoma of the abdominal wall is extremely rare. Percutaneous core needle biopsy is important for the differential diagnosis with more common and biologically more aggressive malignancies, such as desmoid tumors and sarcomas, and may be relevant for planning the most appropriate management.

Abstract Context.—Although there is evidence that endometriosis results from basal endometrium dislocation, the underlying biology is not fully understood. One protein that plays an important role in regulating epithelial proliferation and differentiation is the 63-kDa membrane protein (p63), which is also a marker of basal and reserve cells in the female genital tract. Objective.—To determine whether p63 is expressed differently in peritoneal endometriosis, endometriomas, and adenomyosis, as well as in deep endometriotic nodules of the rectovaginal septum and abdominal wall. Design.—This study includes a prospective series of consecutive patients (Canadian Task Force classification II-2) from a tertiary care university hospital. Specimens collected from 83 patients (15 peritoneal endometriosis specimens, 22 endometrioma specimens, 36 adenomyosis specimens, and 10 rectovaginal septum/abdominal wall specimens) were evaluated. Diagnostic and operative laparoscopies or laparotomies were performed, and tissue samples were obtained. Immunohistochemistry was used to evaluate p63 expression. Results.—Positivity for p63 was detected in 93.3% of the peritoneal endometriosis specimens, 81.8% of the endometrioma specimens, 36.1% of the adenomyosis specimens, and none of the rectovaginal/abdominal wall endometriosis specimens (P < .001). Distribution of p63 immunostaining in the positive specimens was homogeneous. Conclusions.—Endometriotic lesions express p63 differently, and some retain the basal/reserve cell immunophenotype. Nevertheless, it remains unclear whether the lack of p63 expression in some lesions is related to the extent of the disease, to its clinical behavior, or to exacerbation of the accompanying symptoms.

A 37-year-old (G4P3) woman was referred to our hospital at 32 weeks of gestation for the evaluation of a fetus with an intrathoracic cystic lesion. Ultrasonography and magnetic resonance imaging revealed that a fetal cystic lesion without a mucosal layer was located in the posterior mediastinum. These findings were consistent with a bronchogenic cyst. At 38 3/7 weeks of gestation, an elective cesarean section was performed because of her previous cesarean section. A female neonate without any external anomalies, weighing 2,442 g, with Apgar scores of 8 and 9, and requiring no resuscitation was born. Four weeks after delivery, the neonate was admitted because of respiratory distress due to mass effect. At right lateral thoracotomy, a 105 × 65 mm of solitary smooth-walled cyst containing serosanguineous fluid was found in the posterior mediastinum, which was excised completely. Histologic examination revealed the diagnosis of the mediastinal gastric duplication cyst. The neonate made an uneventful recovery. Accurate diagnosis is not necessary, but detection and continuous observation are logical. Although gastric duplication, particularly intrathoracic, is a rare pathology, it should be considered in the differential diagnosis of any intrathoracic cyst.

Primary liver tumors are one of the most common types of malignant neoplasms. Surgical excision is still the most effective treatment in the early stages of the disease, however in most cases early diagnosis is difficult. Moreover, even if the treatment is carried out according to a radical program, the risk of relapse remains extremely high. In this regard, the search for new strategies for the treatment of liver malignancies that differ from traditional methods of treatment is not terminated. One of such promising approaches is immunotherapy. The present review is devoted to the current understanding of the mechanisms of action and the available clinical experience in the use of immunotherapy approaches in the treatment of liver malignancies. Combining different types of immunotherapy or combining immunotherapy with traditional therapeutic approaches can facilitate a synergistic effect and contribute to the development of personalized medicine.

ABSTRACT Objective: to study the characteristics of women undergoing abdominal surgery with suspected abdominal wall endometriosis or abdominal wall tumor, and to assess the association with age, race and previous cesarean delivery. Method: retrospective and analytical study carried out from January 2000 to December 2019, at the General Surgery Service of Hospital Universitário Antônio Pedro (HUAP) at Universidade Federal Fluminense (UFF). Medical records of 100 patients with abdominal wall endometriosis and other types of abdominal wall tumors were analyzed. Age, color, previous history of cesarean section or abdominal surgery and histopathological data were verified. The patients were classified as young adults (aged between 18 and 28 years and 11 months) and adults. The SPSS program was used for data analysis, Fisher’s test with a significance level of 0.05. Results: abdominal wall endometriosis with histopathological confirmation was found in 22%, the mean age was 52.28 ± 18.66 which was lower when compared to other diagnoses. There was an association between previous cesarean section and abdominal wall endometriosis (p <0.005). Conclusion: the women with a diagnosis of abdominal wall endometriosis had undergone previous cesareans (the majority) and were in an active reproductive age. Although the brown skin women were the most frequent, there was no statistical difference.

Abstract Aim To analyze the incidence and risk factors of surgical site infections (SSI) and wound dehiscence (WD) after closure of primary midline laparotomies with small-bites (SB) technique. Material and Methods Retrospective analysis using hospital prospective database of all midline abdominal wall closures (AWC) with SB technique performed in a University Hospital between December 2019 and February 2021. To achieve a proper protocol of AWC with SB technique, it is advised to have suture/wound length (SL/WL) – ratio of more than 4:1. Statistical analysis of the incidence of SSI and AWD, comparing the results when the protocol was properly used (A group) or not (B group), was performed. Between groups, no relevant differences were observed for patient characteristics. Results A total of 108 midline laparotomies were included for analysis. 55.5% of patients were male. The mean age was 62.8 years, mean body mass index was 24.3 kg/m2. 78.7% (85/108) were operated electively. SSI and WD have been recorded in 7 (6.5%) and 8 (7,4%) cases respectively. In 65 (60,2%) patients abdominal wall closure after primary laparotomy was achieved with proper protocol (group A). Median SL/WL in A and B group was 4.57 and 3.43 respectively. The rate of WD in A group (n = 1, 1,5%) was significantly (P=.006) lower than in B group (n = 7, 16,3%). Incidence of SSI was 7,7% (n = 5, A group) vs. 4,7% (n = 2; B group) (P=.420). Conclusions Using a proper AWC protocol has been effective to prevent WD in midline laparotomy.

Initial Clinical Evaluation

Primary malignancy of the urachal remnant is a rare neoplasm that accounts for less than 0.01% of all adult cancers, with an estimated annual incidence of 1:5 million. The tumour carries a grave prognosis that attests to its highly aggressive nature. Owing to its extra-peritoneal location, the tumour runs a relatively silent clinical course until late presentation, when most patients display extensive local invasion and metastatic spread. In this report, we highlight a case of primary malignancy of the urachus that on initial clinical evaluation masqueraded as a Sister Mary Joseph’s nodule. Characteristic imaging features, however, proved decisive in establishing the diagnosis of a urachal carcinoma.
