ABSTRACT
Background: Cutaneous adnexal tumors (CATs) are a large group of neoplasms of the skin and the pathological diagnosis can be challenging. Objective: The aim of this study was to examine clinicopathological features of malignant cutaneous adnexal tumors (MCATs) and to identify therapeutic and prognostic implications. Materials and Methods: Twenty-six patients diagnosed with MCATs and operated in our center were included. Demographic and clinical characteristics of patients, tumor size, histological subtype, perineural and lymphovascular invasion, re-excision status, lymph node metastasis, distant metastasis, recurrence, follow-up, and treatment choice were recorded. All lesions were excised with 1 to 2-cm surgical margin. Surgical margin was determined according to tumor size. Results: Of 26 patients, 14 were males and 12 were females (median age: 66 years). Median follow-up was 52.08 months. Tumor location was the face in 69.2% (n = 18) patients, followed by scalp and neck region. Four patients had coexisting skin tumors. Majority of MCATs (69.2%, n = 18) originated from sweat glands. Median tumor diameter was 4 (range, 0.8 to 17) cm. There was a statistically significant correlation between presence of perineural invasion and advanced disease (P = 0.036). Majority of the patients had Stage 1-2 disease, while two patients had Stage 4 disease. In six patients (23.1%), re-excision was performed due to surgical margin positivity. Conclusion: Incidence of MCATs has an increasing trend with advanced age and these tumors are more commonly seen in men and in visible sites of the body such as head and neck and scalp. Wide resection according to tumor size is the first-line treatment.
ABSTRACT
Objectives: The aim of this study was to examine the impact of performing surgeries with necessary precautions and to evaluate demographic characteristics of operated patients during novel coronavirus-2019 (COVID-19) pandemic and the infection rates during hospitalization and within 14 days after surgery. Material and Methods: Between March 15th, 2020 and April 30th, 2020, a total of 639 patients who had been operated on in our center were retrospectively analyzed. According to the triage system, the surgical procedures were classified as emergency, time-sensitive, and elective procedures. Data including age, sex, indication for surgery, the American Society of Anesthesiologists (ASA) class, pre- and postoperative symptoms, the presence and/ or absence of reverse transcriptase-polymerase chain reaction (RT-PCR) test result, type of surgery, surgical site, and documented COVID-19 infections during hospitalization and within 21 days after surgery were recorded. Results: Of the patients, 60.4% were males and 39.6% were females with a mean age of 43.08 ± 22.68 years. Malignancy was the most common indication for surgery (35.5%), followed by trauma (29.1%). The abdominal area and head and neck region were the most frequent surgical sites in 27.4% and 24.9% of the patients, respectively. Of all surgical procedures, 54.9% were emergency and 43.9% were time-sensitive procedures. Of the patients, 84.2% were in ASA Class I-II while 15.8% patients were in ASA Class III, IV and V. General anesthesia was the most common anesthesia type in 83.9% of the patients. The overall rate of COVID-19 infection was 0.63% in the preoperative period. The rate of COVID-19 infection during and after surgery was 0.31%. Conclusion: With similar infection rates to the general population, surgeries of all types can be performed safely taking preventive measures in the preand postoperative period. It would be wise to perform surgical treatment without delay in patients with an increased risk for mortality and morbidity in accordance with strict infection control principles.
ABSTRACT
INTRODUCTION: Lipomas are the most common benign soft tissue tumors and appear in any part of the body. They typically consist of mature adipose tissue. Osteolipoma is an extremely rare histologic variant of lipoma that contains mature lamellar bone within the tumor and osteolipoma independent of bone tissue are very rare. We report a case of histologically confirmed osteolipoma independent of bone located in the thigh. CASE PRESENTATION: A 47-year-old male presented with a progressively enlarging, painful mass which approximately 10 cm x 8 cm over the anteromedial aspect of his right thigh. Plain films, Computerized Tomography, Magnetic Resonance Imaging and ultrasound guided needle biopsy were performed. Given the benign imaging characteristics and fine needle aspiration, an excisional biopsy was undertaken. The definitive pathologic diagnosis was intramuscular osteolipoma without evidence of malignancy. No recurrence was observed after 18 months follow up. CONCLUSION: Although ossifying lipomas are very rare, it is important to keep them in mind when a lesion with adipose tissue in combination with ossification is encountered.
ABSTRACT
Fibrous dysplasia of bone is an enigma with no known cure. Treatment currently consists of curettage and bone-grafting in an attempt to eradicate the lesion and to prevent progressive deformity. This study presents the results of prophylactic intramedullary nailing in 10 patients with monostotic fibrous dysplasia, pain increasing with movement, and scintigraphically established activity. Ten patients with monostotic fibrous dysplasia in their upper or lower extremities treated between 2001 and 2003 were included in the study. Seven patients were male and 3 were female; their mean age was 26.9 years. The mean duration of follow-up was 33.5 months. Closed intramedullary nail without reaming was used in all cases. Bone grafting was not performed. Patients were allowed full weight bearing on the affected extremities on the second postoperative day. Mean VAS for functional pain was 5.33 +/- 0.65 preoperatively and 2.26 +/- 0.57 at final follow-up (p < 0.05). Radiographs showed no changes in lesion size, and the intramedullary fixation appeared to be stable. Prophylactic intramedullary nailing appeared to be beneficial in monostotic fibrous dysplasia with scintigraphically proven activity and functional pain. It also avoids problems that may occur following pathological fracture.
