Encysted Tubular Sweat Gland Adenoma of the Nasal Ala: A Rare Cause for Unilateral Nasal Discharge.

Benign cutaneous apocrine sweat gland adenomas in the nose are rare. We present the novel case of a nasal ala cutaneous sweat gland lesion. A 43-year-old male presents with a one year history of a right nostril mass with intermittent clear discharge, triggered by periods of hot weather and increased humidity.

Pulmonary Mucoepidermoid Carcinoma With Multiple Paraneoplastic Syndromes.

Pulmonary mucoepidermoid carcinoma (PMEC) is rare and challenging to diagnose. Its association with paraneoplastic syndromes is poorly described. It is also uncommon for a patient with lung cancer to present with multiple paraneoplastic syndromes.

A Case of Inflammatory Pseudotumour Masquerading as Hepatocellular Carcinoma.

Inflammatory pseudotumors (IPTs) of the liver can mimic malignant lesions. As the name implies, they are usually associated with an inflammatory process and usually regress with the treatment of the underlying pathology. We report a case of a 67-year-old female who presented with right upper quadrant pain, deranged liver enzymes, elevated tumor markers [alpha-fetoprotein (AFP) and CA 19-9], and a large liver mass on imaging, suspected to be hepatocellular carcinoma (HCC).

A Case of Pulmonary Nodular Lymphoid Hyperplasia Responding to Corticosteroid Treatment.

Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare non-neoplastic disease that presents with mass lesions in the lung. It is radiologically difficult to differentiate it from adenocarcinoma of the lung or pulmonary lymphoma. There has been no consensus regarding the treatment of PNLH; however, in many case series, patients usually undergo surgical resection for diagnostic and therapeutic purposes.

Virtual Multidisciplinary Review of a Complex Case Using a Digital Clinical Decision Support Tool to Improve Workflow Efficiency.

Objective: Integration of distinct clinical perspectives in multi-disciplinary tumor board meetings is critical to determine optimal patient care. Digital tools can support the data consolidation needed for meeting preparation and data sharing during complex case reviews. In this paper, we assessed the value of a clinical decision support tool on workflow efficiency and conducting a complex case review of a dermatofibrosarcoma protuberans (DFSP) tumor.

Isolated IgG4-related gastric disease presenting as diffuse gastric wall thickening with ulcer.

An 81-year-old male presented with loss of appetite, early satiety and iron deficiency anaemia. A computed tomography (CT) scan of the abdomen and pelvis during initial work-up revealed diffuse gastric mural thickening associated with a large ulcer and adjacent gastro-hepatic lymphadenopathy. The CT appearances, together with the clinical features, were highly suspicious for an infiltrative type of gastric malignancy.

Serum IgG2 and tissue IgG2 plasma cell elevation in orbital IgG4-related disease (IgG4-RD): Potential use in IgG4-RD assessment.

Aims: To determine the role of serum and tissue IgG2 in orbital biopsies with the histological features of IgG4-related disease (IgG4-RD) in comparison with non-IgG4-related orbital inflammatory disorders (OID), including autoimmune disorders.

Methods: This is an international (Sheffield, UK, and Singapore) collaborative, retrospective case review of 69 patients (38 from Singapore National Eye Centre and 31 from Royal Hallamshire Hospital, Sheffield) with orbital inflammatory biopsies between 2002 and 2016. Clinical information and histology were reviewed and cases were classified into three groups: Group 1: IgG4-RD orbital inflammation (n=43); Group 2: idiopathic OID (n=12) and Group 3: autoimmune OID (n=14).

The association of lacrimal gland inflammation with alopecia areata.

Purpose: To describe the association of lacrimal gland inflammation with alopecia areata.

Methods: We reviewed the medical records of 4 patients diagnosed with lacrimal gland inflammation who had an antecedent or subsequent episode of alopecia. Data was collected on the presentation age, gender, medical history, disease onset, symptoms and signs, imaging, histopathology, systemic evaluation, management and outcome.

'Prechronous' metastasis in clear cell renal cell carcinoma: a case report.

Introduction: Although metastatic carcinoma in the presence of an occult primary tumor is well recognized, underlying reasons for the failure of the primary tumor to manifest are uncertain. Explanations for this phenomenon have ranged from spontaneous regression of the primary tumor to early metastasis of the primary tumor before manifestation of a less aggressive primary tumor. We report a case of 'prechronous' metastasis arising from clear cell renal cell carcinoma, where metastatic disease initially manifested in the absence of a primary renal tumor, followed by aggressive growth of the primary renal lesion.

Bilateral orbital varices: an approach to management.

The authors report a case of bilateral orbital varices in a 19-year-old man with a 7-year history of intermittent left proptosis and dystopia. CT demonstrated enhancing lesions with phleboliths and gadolinium-enhanced MRI showed characteristic hyperintense lesions. The asymptomatic right lesion was treated conservatively; the left lesion was excised following intralesional injection of cyanoacrylate.

Epibulbar osseous choristoma: a report of two cases.

Epibulbar osseous choristoma occurs rarely and is commonly mistaken for a dermoid or dermolipoma. We report two cases: an 8-year-old boy and a 79-year-old lady with epibulbar osseous choristomas where computed tomography showed an extraocular lesion in the temporal quadrant and diagnosis was confirmed by excision biopsy. The osseous component was adherent to the sclera in the young patient, while it was loosely attached to the surrounding tissue in the older patient.
