Juvenile psammomatoid ossifying fibroma of maxilla: A case report

Juvenile psammomatoid ossifying fibroma is histological variant of juvenile ossifying fibroma, a fibro-osseous tumor of craniofacial bones with benign but potentially aggressive nature. Complete excision of tumor is essential as it is associated with very high recurrence rate. We have reported here a case of juvenile ossifying fibroma- a psammomatoid variety present in right maxilla in a 13-year old male child. Complete excision of tumor was done through intra-oral approach with the 2.5 years of follow up shows no recurrence.Juvenile psammomatoid ossifying fibroma is fibro-osseous tumor of craniofacial bones with benign but potentially aggressive nature. Complete excision of tumor is essential as it is associated with very high recurrence rate.

Clinical Analysis of 44 Cases of Atypical Polypoid Adenomyoma of the Uterus

Background: Atypical polypoid adenomyoma (APA) is a rare intrauterine polypoid lesion that occurs predominantly in premenopausal women. Although, it is considered as a benign lesion and treated conservatively previously, more and more cases show that APA has a high rate of recurrence or residual, and is found to precede the development of carcinoma. The clinical management of APA remains to be established. The aim of this study was to analyse the clinicopathological features of APA and discuss its diagnosis and prognosis.Methods: Forty-four patients with APA were admitted to Beijing Obstetrics and Gynecology Hospital from 2005-2019, and their clinical and histopathologic features were evaluated. B-ultrasound was performed, and all patients (n=44) underwent hysteroscopy. Endometrium excision was performed by means of the “Four-step diagnosis and treatment” method. Hysteroscopic transcervical resection (TCR) was performed in 5 cases with APA-H and 11 with APA-L. Except for one patient who underwent transcervical endometrial resection, all patients underwent hysterectomy and salpingectomy or salpingo-oophorectomy. Data from a median follow-up of 42 months (ranging from 3 to 174 months) were available for these patients.Results: Pathological diagnoses were made according to the degree of abnormality of APA surface glands, resulting in APA-L in 36 cases and APA-H in 8 cases. Among these cases, 28 (25 APA-L and 3 APA-H) were treated conservatively. “Four-step diagnosis and treatment” method performed a excellent effect for APA therapy. During the follow-up no evidence of recurrence was found.Conclusions: For cases with intracavitary lesions > 1 cm, hysteroscopic “four-step diagnosis and treatment” and pathological diagnosis are the basis of clinical treatment. More than 30% of APA surface glands have complex structures, characterized by branching and budding, or other high-risk factors, such as endometrial hyperplasia, which are indications for hysterectomy. For patients with the desire to become pregnant or for uterine preservation, hysteroscopy with complete excision of the lesions should be the preferred treatment method. The patients should be treated individually, followed up closely, and followed up by regular hysteroscopy and endometrial biopsy.

Curative Intent Surgery of Oral Malignant Melanoma and Regional Lymph Node Biopsy Assessment in 25 Dogs: 2006–2017

Medical records were searched for dogs that had received curative intent surgery for oral malignant melanoma and ipsilateral excisional regional lymph node biopsy. Twenty-seven dogs were operated on and 25 dogs of these dogs met the inclusion criteria of signalment, post-excision margin status, presence of metastasis for each biopsied lymphocentrum, survival time post-excision, presence of recurrence or metastasis at follow-up or at death/euthanasia, location of the primary tumor, and any postoperative adjuvant treatment. These 25 dogs had complete tumor excision with tumor-free margins and 19 (76%) had postoperative adjuvant therapy. Median survival time after excision for the dogs in this study was 335.5 days. Results of this study support previous work that documents prolonged survival time following complete excision of oral malignant melanoma with tumor-free surgical margins in dogs. Additionally, 4 dogs (16%) had histologically confirmed regional lymph node metastasis at the time of definitive surgery.

A large and invasive pleomorphic adenoma of nasal cavity: a rare case report and review of literatures

Background Pleomorphic adenomas are common tumors of major salivary glands. However, the localization in nasal cavity originating from the lateral wall is exceptional. This work is a presentation of a very rare case that presents the diagnostic challenge, considering the multitude of malignant and benign differential diagnosis. A discussion of surgical approach, and the possible complications associated with it. Case presentation This is the case of an invasive nasal pleomorphic adenoma in a 48-year-old patient; the patient underwent complete excision through combined left lateral rhinotomy and functional endoscopic sinus surgery. Conclusion Pleomorphic adenoma is a very rare benign tumor of the nasal cavity. Clinical diagnosis is generally difficult regarding the multitude of differential diagnosis. Confirmation is established upon histological aspect. This is a case of a very rare large pleomorphic adenoma of nasal cavity originating from the lateral wall, associated with differential diagnosis, and surgical approaches, as well as perceivable complications. The strength of this work is to point out the importance of complete surgical extirpation and thorough follow-up to prevent recurrences and malignant transformation.

Brainstem Cavernous Malformations Management: Microsurgery vs. Radiosurgery, a Meta-Analysis

Given the rareness of available data, we performed a systematic review and meta-analysis on therapeutic strategy microsurgical resection and stereotactic radiosurgery (SRS) for brainstem cavernous malformations (BSCMs) and assessed mortality, permanent neurological deficits (PNDs), rebleeding rate, and patients who require reintervention to elucidate the benefits of each treatment modality. Preferred reporting items for systematic reviews and meta-analyses (PRISMA) were used for protocol development and manuscript preparation. After applying all inclusion and exclusion criteria, six remaining articles were included in the final manuscript pool. In total, this meta-analysis included 396 patients, among them 168 patients underwent microsurgical treatment and 228 underwent SRS. Findings of the present meta-analysis suggest that regarding the total group of patients, in terms of mortality, late rebleeding rate, and PNDs, there was no superiority of the one method over the other. Applying the leave-one-out method to our study suggests that with low robust of the results for the bleeding rate and patients who require reintervention outcome factor, there was no statistical difference among the surgical and SRS treatment. Microsurgical treatment of BSCMs immediately eliminates the risk of rehemorrhage; however, it requires complete excision of the lesion and it is associated with a similar rate of PNDs compared with SRS management. Apparently, SRS of BSCMs causes a marked reduction in the risk of rebleeding 2 years after treatment, but when compared with the surgical treatment, there was not any remarkable difference.

Peripheral Odontogenic Fibroma- Case Series of a Rare Benign Tumor

Peripheral odontogenic fibroma (POdF) is a rare benign odontogenic tumor of ectomesenchymal origin which is composed of fibrous connective tissue containing islands, strands or cords of odontogenic epithelium. The lesion is more common among females, commonly seen between the second to fourth decades of life, mostly affecting the anterior region of mandible. Clinically, it may present similar characteristics with other more common gingival lesions such as pyogenic granuloma, peripheral ossifying fibroma and peripheral giant cell granuloma. So, histopathological examination is required for accurate diagnosis. We present here three rare clinical cases of peripheral odontogenic fibroma and their management by complete excision of the lesion with good postoperative outcomes.

Leiomyoma of the anterior vaginal wall: a rare case

Background: Leiomyoma is a benign smooth muscle mesenchymal tumor, usually of uterine origin but may rarelydevelop in the vaginal walls. Case presentation: A case of 40-year-old para 5+0 woman with anterior vaginal wall leiomyoma is reported. Thepresentation mimics that of uterovaginal prolapse and hence presents a diagnostic challenge. The unusualappearance of the protrusion, failure to reduce at any time even while lying down, and complete absence of urinarysymptoms raised the suspicion of a rare case. The diagnosis was made through examination under anesthesia,cystoscopy, and biopsy. Histological examination of the biopsy specimen confirmed vaginal wall leiomyoma. Thepatient had complete excision of the mass without any complications. Discussion and Conclusion: Vaginal wall leiomyoma is a rare benign vaginal lesion that can easily bemisdiagnosed. Diagnosis involves critical clinical evaluation, especially during pelvic examinations. Any vaginalprotrusion should be approached with a high index of suspicion, especially in patients of reproductive age.

Oncogenic osteomalacia secondary to hemangiopericytoma: a case report

<p>We are going to present a case of hypo-phosphatemic rickets secondary to phosphaturic mesenchymal tumour who came with complaints of proximal muscle weakness which limited his effort tolerance and activities of daily life like standing from squatting position and rib pain. His FGF-23 levels were very high above normal levels and PET CT revealed a well-defined enhancing lesion abutting femoral neurovascular bundle. After consultation with endocrinologist, we have d done complete excision of the mass. Post-surgery all symptoms were relieved, proximal muscle strength improved gradually and serum levels of phosphorus, ALP and FGF-23 came back to normal.</p>

The Glans Schwannoma: A Rare Clinical Entity

Introduction: Schwannoma of the glans is a rare clinical entity. The diagnosis is histological. Treatment is surgical, with complete excision. The authors report this rare case encountered at the University Hospital of Libreville in order to identify its clinical and therapeutic characteristics. Observation: Mr. I.B, 50 years old, with no medical-surgical history, consulted for swelling of the glans evolving for 06 years, preventing coitus. He reported a notion of poor healing from an acorn sore after the trouser fly was closed. The diagnostic suspicion was a glans keloid. A complete resection was performed. Histologic examination favored a glans schwannoma. Healing was effective on D7 postoperatively. Erectile functions have been preserved. Conclusion: The glans schwannoma is rare. Surgical treatment gives good results.
