Spontaneous testicular hemorrhagic necrosis is a rare disease usually associated with testicular torsion. Partially involved and suspicious testis tumor cases are also defined from orchiectomy specimens. Herein, a spontaneous hemorrhagic necrosis, without any testicular torsion, but with involvement of the whole testicle and epididymis, is reported. A 21 year old patient, who presented with a painless left testicular enlargement of several days duration was believed, based on physical examination, ultrasonography and elevation of serum LDH, to have a testicular tumor. Diagnosis was made only after radical orchiectomy and histopathological examination.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

PURPOSE: This study investigated the clinical and radiological outcomes of patients undergoing provisional fixation in conjunction with locking plate fixation. Miniplates were used as the reduction plates for the surgical treatment of severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. MATERIALS AND METHODS: The radial length, radial inclination, volar tilt, and radial intra-articular step-off were measured preoperatively, postoperatively, and at one year after surgery in 12 patients (eight males, four females, mean age 55.4 years old). The patients underwent volar locking plate fixation with miniplate as a reduction plate for severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. Clinical evaluations were conducted using the modified Mayo wrist score (MMWS). RESULTS: Bone union was achieved in all cases. The mean MMWS was 81.8 points, including two excellent, three good, and seven fair cases. Radiological improvements were observed in the average radial length (preoperative, 6.4 mm; postoperative, 11.8 mm), average radial inclination (10.2° to 22.4°), average volar tilt (−4.5° to 10.6°), and average radial intra-articular step-off (4.8–0.8 mm) (all, p<0.05). Radiographic measurements obtained immediately after surgery and at the final follow-up revealed insignificant decreases in radial length (0.6 mm), radial inclination (0.4°), and volar tilt (0.9°) (all, p>0.05). CONCLUSION: Miniplate fixation can be an effective treatment option as a reduction plate for the treatment of distal radial fractures, which is challenging to reduce and maintain due to severely comminuted metadiaphysis fractures with the intra-articular fracture.

Fordyce's disease is a condition known as ectopically located sebaceous glands on the vermilion borders of the lips and oral mucosa. Clinically, it is groups of minute, yellowish, globoid macules and papules. Histologically, it is characterized by sebaceous glands not associated with hair follicles. We report on a 40-year-old man with Fordyce's disease showing particularly wide distribution on the buccal mucosa and upper lip.

Purpose: To analyze various prognostic factors and surgical outcomes in patients who underwent radical nephrectomy and thrombectomy of a renal cell carcinoma with renal vein or inferior vena caval thrombosis. Materials and Methods: Among 44 patients with confirmed renal cell carcinomas and renal vein or inferior vena caval thrombosis, between December 1993 and June 2000, 42 having undergone radical nephrectomy and thrombectomy were retrospectively studied. 2 patients were excluded due to no operation performance. The 5-year disease-specific survival rates were analyzed according to various prognostic factors, including age, gender, clinical symptoms, tumor side (Rt. vs. Lt.), thrombus position (renal vein vs. IVC), histopathological cell type, lymph node involvement, pT stage irrespective of thrombus, Fuhrmann nuclear grade and invasion to perinephric fat, vessel, renal pelvis or adrenal gland. Results: The overall 5-year disease-specific survival rate of all the patients was 55%. A univariate analysis of the 42 patients showed that the position of the tumor thrombus, histopathological cell type and invasion to the adrenal gland had a significant impact on the survival. On multivariate analysis, the tumor thrombus location and histopathological cell type were independent prognostic factors for the survival. The 5-year disease-specific survival rates of the patients with a renal vein thrombus (n=23) and with IVC (inferior vena cava, n=20) were 75 and 20%, respectively. The 5-year disease-specific survival rate of the patients with a conventional cell type (n=32) was 68%, and patients with other pathologic cell types had no significant follow-up periods. Conclusions: The tumor thrombosis position, histopathological cell type and invasion to the adrenal gland are considered as clinically significant prognostic factors in patients with a renal cell carcinoma with vein thrombosis after radical nephrectomy with a thrombectomy. Meticulous radical nephrectomy with thrombectomy will be beneficial to the survival of patients with a renal cell carcinoma and vein thrombus.

BACKGROUND: The execution of fibular allograft augmentation in unstable proximal humerus fractures (PHFs) was technically demanding. In this study, the authors evaluated the clinical and radiographic outcomes after tricortical iliac allograft (TIA) augmentation in PHFs. METHODS: We retrospectively assessed 38 PHF patients treated with locking-plate fixation and TIA augmentation. Insertion of a TIA was indicated when an unstable PHF showed a large cavitary defect and poor medial column support after open reduction, regardless of the presence of medial cortical comminution in preoperative images. Radiographic imaging parameters (humeral head height, HHH; humeral neck-shaft angle, HNSA; head mediolateral offset, HMLO; and status of the union), Constant score, and range of motion were evaluated. Patients were grouped according to whether the medial column support after open reduction was poor or not (groups A and B, respectively); clinical outcomes were compared for all parameters. RESULTS: All fractures healed radiologically (average duration to complete union, 5.8 months). At final evaluation, the average Constant score was 73 points and the mean active forward flexion was 148°. Based on the Paavolainen assessment method, 33 patients had good results and 5 patients showed fair results. The mean loss of reduction was 1.32 mm in HHH and 5.02% in HMLO. None of the parameters evaluated showed a statistically significant difference between the two groups (poor and not poor medial column support). CONCLUSIONS: In unstable PHFs, TIA augmentation can provide good clinical and radiological results when there are poor medial column support and a large cavitary defect after open reduction.

PURPOSE: Bevacizumab has been used as a promising drug for metastatic colorectal cancer in combination with chemotherapeutic agents. However, it has a few serious adverse effects, such as intestinal bleeding or perforation. The purpose of this study is to identify the clinical characteristics of intestinal perforation induced by bevacizumab in colorectal cancer patients.METHODS: From January 2007 to June 2018, a total of 488 patients underwent chemotherapy with bevacizumab for metastatic colorectal cancer. Medical records were reviewed retrospectively.RESULTS: Nine patients (1.8%) were identified with intestinal perforation induced with bevacizumab. The median age was 59 years (range, 36–68 years). The primary tumor site was the sigmoid colon in six patients, the rectum in three patients. The liver was the most common metastatic organ (7 patients). Perforation sites were primary tumor site of the colorectum in four patients and the small bowel in five patients. Intestinal perforation was developed after a median of 3 chemotherapy cycles (range, 1–15 cycles), and a median of 7 days (range, 3–32 days) after chemotherapy. One patient expired due to sepsis.CONCLUSION: Bevacizumab induced intestinal perforation is a lethal adverse effect in patients with colorectal cancers. The characteristics of intestinal perforation varied according to perforation site, previous chemotherapy cycles, and clinical course. Careful monitoring is necessary with the use of bevacizumab in conjunction with chemotherapeutic agents.
