Article Abstract
The formation of symptomatic intradural mucocele associated with a paranasal osteoma is rare, and no standard treatment has been established. Here, we present a case of intradural mucocele in a 27-year-old man complaining of headache and generalized convulsion. Cranial CT and brain MRI showed a left frontoethmoidal osteoma extending into the left anterior cranial fossa and orbit along with a mass in the left frontal lobe. He underwent resection of both intracranial osteomas and the mass through left frontal craniotomy. Histological findings were consistent with a mucocele, and the diagnosis of an intradural mucocele associated with a frontoethmoidal osteoma was confirmed. The postoperative course was uneventful. Although both osteoma and mucocele are benign, they may cause life-threatening symptoms by expanding intracranially. A tailored treatment considering the invasiveness and postoperative long-term follow-up of the patient is essential for this uncommon condition.

Gallbladder mucocele (GBM) is one of the most common gallbladder disorders in dogs. Recent studies have suggested a potential association between GBM development and reduced expression of anion channel-related molecules in gallbladder epithelial cells. However, further investigation has been limited due to the lack of an effective in vitro culture system to validate the functions of the molecules.

Aims: Mucocele-like lesions (MLL) of the breast are rare. MLL associated with flat epithelial atypia (FEA) or atypical ductal hyperplasia (ADH) is classified as MLL with atypia (AtypMLL). We study the upgrade rate and long-term outcomes in AtypMLL, focusing on the extent and type of atypia in needle biopsy (NB).

Introduction: Mucoceles are benign, slow-growing cystic formations located within the paranasal sinuses, caused by complete ostial obstruction and accumulation of mucous secretions. Here, we report a case of a patient who initially presented with unilateral painless visual impairment and was ultimately diagnosed with bilateral sphenoid sinus mucoceles (SSMs) after two hospitalizations.
Case Presentation: A 67-year-old woman presented with a 7-day history of decreased vision in her left eye.
Evaluation of Cytokeratin 19 Expression in Oral Carcinogenesis.

Background & Objective: Oral squamous cell carcinoma (OSCC) accounts for over 90% of oral cancers. Cytokeratin 19 (CK19), produced by suprabasal epithelial cells, reflects alterations in cellular behavior and has been associated with premalignant changes in the oral epithelium. This study aimed to evaluate the expression of CK19 in OSCC and oral epithelial dysplasia (OED) and its potential role in oral carcinogenesis.

Maxillary antral mucoceles are rare complications of chronic inflammation of the sinus mucosa due to infection or trauma that leads to an obstructed sinus outflow, such as allergic fungal rhinosinusitis. Treatment of choice of AFRS is medical therapy associated with functional endonasal endoscopic surgery; surgical evacuation (preferentially using endoscopic approach) of mucocele is resolutive in most cases. We think that in cases of giant maxillary mucocele Caldwell Luc approach should be avoided even in case of facial soft tissues (including the orbit) or pterygomaxillary fossa involvement, since endoscopic approach can provide adequate surgical field reducing complication rate and sequaelae.
