Mucosal Spread of Sinonasal Adenocarcinoma into the Nasolacrimal Duct Without Bony Erosion of the Nasolacrimal Canal: A Case Report.

Sinonasal malignancy is a rare but recognized cause for nasolacrimal obstruction leading to epiphora. While direct mucosal spread through the nasolacrimal duct can occur in benign sinonasal tumors such as inverting papilloma, the same phenomenon has not been described in malignant lesions. The authors present a case of a low-grade nonintestinal type sinonasal adenocarcinoma centered on the inferior meatus of the sinonasal cavity, showing mucosal invasion into the nasolacrimal duct with bony expansion but no erosion of the nasolacrimal canal.

Incidental Solitary Myofibroma in a Young Adult Female Patient: A Case Report and Comprehensive Literature Review of Myofibroma in Adults.

Myofibroma is a rare mesenchymal tumor typically observed in children, with only a few reported cases in adults. It can be easily mistaken for more common benign lesions, making it essential to include them in the differential diagnosis of soft tissue masses. This case report presents a rare instance of myofibroma in a young adult, and a comprehensive review of the literature presenting case reports and case series of myofibroma cases in the head and neck regions of adult patients aged > 18 years.

Seromucinous hamartoma with unique clinical and histopathological features: a case report and review of the literature.

Background: We present this case to highlight the importance of considering seromucinous hamartoma in the differential diagnosis of nasal cavity lesions, particularly due to its rarity and potential for being mistaken for more aggressive pathologies. Seromucinous hamartoma, although benign, can exhibit clinical and histological features that overlap with those of malignant tumors, posing a diagnostic challenge. This case is especially noteworthy due to the unusual presentation of sebaceous differentiation within seromucinous hamartoma, a feature not previously documented in the literature.

Central pancreatectomy: An uncommon but potentially optimal choice of pancreatic resection.

Benign, premalignant or low-grade malignant pancreatic tumors are increasingly diagnosed owing to the widespread uptake of cross-sectional imaging. Surgical excision is a potential treatment option for these tumors. Pancreatoduodenectomy and distal pancreatectomy are the standard resections for tumors located in the pancreatic head-neck or body-tail, respectively, and not uncommonly sacrifice a significant amount of healthy pancreatic parenchyma.

Objective: The objective of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of AI-assisted technologies, including endoscopy, voice analysis, and histopathology, for detecting and classifying laryngeal lesions.

Methods: A systematic search was conducted in PubMed, Embase, etc. for studies utilizing voice analysis, histopathology for laryngeal lesions, or AI-assisted endoscopy.

Endocervical Polyp as a Cause of Genital Bleeding in the Second Half of Pregnancy: A Case Report.

Cervical polyps are typically benign exophytic lesions that are often asymptomatic and small during pregnancy. However, they can occasionally cause significant symptoms, leading to gestational complications. A lack of awareness of this condition, combined with inadequate diagnosis and treatment, can pose risks to maternal and fetal health, potentially resulting in complications or pregnancy loss.

Chondroid syringoma on the nasal wing: A case report in a 22-year-old male.

Introduction And Importance: Chondroid syringoma also referred to as a mixed tumor, is a benign and rare tumor originating from apocrine or eccrine sweat glands; it predominantly affects middle-aged men. While fine-needle aspiration cytology can aid in diagnosis, histological confirmation remains essential due to the potential for misdiagnosis.

Case Presentation: A-22-year-old male who presented with a solitary, slow-growing, painless, erythematous nodule on the right nasal wing that had been present for 1 year, which was misdiagnosed as an epidermal cyst.

Surgical Management of Epidermoid Cysts of Scalp: A Case Report.

Epidermoid cysts represent a common benign cutaneous neoplasm resulting from the invagination and subsequent proliferation of epidermal cells within the dermal layer. They exhibit a predilection for the face, cervical region, upper torso, and scalp, manifesting as firm, mobile nodules with a characteristic central punctum. Surgical excision is the recommended therapeutic approach for sizeable or recurrent cysts, particularly when they elicit discomfort or aesthetic concerns.

The Importance of Elastography in the Early Diagnosis of Highly Differentiated Parotid Tumors: a Case-Report.

It is indisputable that high-resolution ultrasound (US) is the diagnostic gold standard for the evaluation of superficial parotid gland diseases. It is a dynamic, quick, simple, easily available, cost-effective, noninvasive procedure, with absence of ionizing radiation examination that can be performed safely and in special categories of patients such as pregnant women and children. It is widely accepted that on US, benign tumors have clear, smooth and well-defined borders, homogeneous hypoechoic parenchyma and a defined distribution of vessels.

Recurrent Nodular Fasciitis of the Oral Mucosa: Case Report and Review of the Literature.

Among all benign and reactive mesenchymal lesions, nodular fasciitis is most frequently misdiagnosed as a sarcoma due to its concerning clinical and histopathological features: it arises on fascial surfaces, grows rapidly, and may infiltrate into adjacent tissues and blood vessels. The most commonly involved sites include upper extremities, trunk, head, and neck, with rare occurrences in the oral cavity. Recurrences following both incomplete and complete excision are rare, and its natural history progresses through self-limited growth followed by spontaneous regression.

Giant benign mesenteric cysts (mesothelioma and lymphangioma): A report of two cases.

Introduction And Importance: Mesenteric cysts are a rare group of intra-abdominal tumors located in the mesentery or omentum, most of this lesion are asymptomatically but occasionally presents with non-specific symptoms, which makes diagnosis difficult.

Case Presentation: We present two cases of giant mesenteric cyst in our Institution, the first case is a women of 23 years with previous gynecologic surgery with chronic abdominal pain and large abdominal mass CT showed a giant intraabdominal 30 × 25 × 15 cm, the patient went to laparotomy and a large mesenteric tumor found. The Histopathology reported a Benign cyst mesothelioma (BCM).

Natural course of the acute unruptured intracranial vertebral artery dissections which show pearl-and-string sign.

Introduction: Ruptured vertebral artery dissections frequently exhibit pearl-and-string signs, a characteristic also observed in many unruptured dissections. This study examines the natural course of 50 unruptured acute vertebral artery dissections presenting with pearl-and-string signs and compares them to 10 ruptured dissections of the same morphological pattern.

Methods: We reviewed 633 radiology reports of head and neck imaging studies that included the keyword 'dissection'.

Ectopic thyroid follicular carcinoma in the right mandible: a case report.

Background: Ectopic thyroid carcinoma in the mandible is extraordinarily rare; few histologically proven cases have been reported in the literature. Embryologically, cases of ectopic thyroid occur with a developmental abnormality during the migration of the thyroid gland from the floor of the primitive foregut to its final position in the neck. Ectopic thyroid tissue can be found around the course of the thyroglossal duct or laterally in the neck, and even in the mediastinum or below the diaphragm.

Case report: Partial regression of metastatic squamous cell carcinoma with altered azathioprine dosage after long-term use in renal transplant patient.

Introduction: We report the partial regression of metastatic squamous cell carcinoma (SCC) after reduction of long-term azathioprine therapy while awaiting surgery. The patient was a 69-year-old man with a history of kidney transplantation. Moderately differentiated SCC arising in the anterior neck was initially diagnosed, followed later by poorly differentiated SCC metastases to cervical lymph nodes.

Computer-assisted discrimination of cancerous and pre-cancerous from benign oral lesions based on multispectral autofluorescence imaging endoscopy.

Significance: Diagnosis of cancerous and pre-cancerous oral lesions at early stages is critical for the improvement of patient care, to increase survival rates and minimize the invasiveness of tumor resection surgery. Unfortunately, oral precancerous and early-stage cancerous lesions are often difficult to distinguish from oral benign lesions with the existing diagnostic tools used during standard clinical oral examination. In consequence, early diagnosis of oral cancer can be achieved in only about 30% of patients.
