Isolated end-stage renal disease in Sjögren’s syndrome due to immune complex mediated glomerulonephritis

Renal involvement is an uncommon extra-glandular manifestation in Sjogren’s syndrome (SS). We present the case of a young male who presented with nephrotic range proteinuria and advanced irreversible renal disease, with positive anti-Ro antibody (Ab) and antineutrophil cytoplasmic antibody (ANCA) with myeloperoxidase (MPO) specificity. He was initially treated with steroids for...

A rare cutaneous adverse effect secondary to cabozantinib therapy

Cabozantinib is a tyrosine kinase inhibitor which is increasingly being used for the treatment of metastatic renal cell cancer. Skin toxicity such as palmar-plantar erythrodysesthesia is not uncommon with such agents. However, bullous skin reactions are not common and we report the case of a patient with metastatic renal cell cancer who experienced such cutaneous toxicity.

Pembrolizumab-induced agranulocytosis in a pulmonary pleomorphic carcinoma patient who developed interstitial lung disease and ocular myasthenia gravis

An 82-year-old man with a recurrence of pulmonary pleomorphic carcinoma was treated with pembrolizumab. He achieved partial response after three cycles of pembrolizumab. However, he developed febrile neutropenia. A bone marrow aspiration sample revealed a decrease of mature neutrophils, and anti-neutrophil antibody was detected in blood. Computed tomography scans revealed...

Appendicitis in non-typhoidal salmonella bacteraemia

Salmonella typhi and paratyphi infections can manifest as acute abdomen due to intestinal perforations, salpingitis and rarely appendicitis. Non-typhoidal salmonella infection that usually only causes self-limiting gastroenteritis, is rarely associated with appendicitis. We present the case of a 78-year-old gentleman with Salmonella bacteraemia complicated by acute appendicitis...

Radiation-induced cystic brain necrosis developing 10 years after linac-based stereotactic radiosurgery for brain metastasis

Cystic brain necrosis (CBN) is a rare form of BN. It typically occurs as a very late complication, and no standard treatment has been established. We report a case of a 59-year-old man who developed CBN 10 years after radiation therapy for metastatic brain tumors. The therapy consisted of whole brain radiotherapy followed by linac-based stereotactic radiosurgery as a boost...

Septic shock secondary to acute bacterial prostatitis in an HIV-positive male: a novel presentation

Acute bacterial prostatitis, an acute infection of the prostate gland, results in lower abdominal pain, flank pain, urinary symptoms and the potential for systemic symptoms like fever and shock. With a high mortality rate if left untreated, acute bacterial prostatitis becomes a true urological emergency, which if allowed to progress, may result in bacteremia, severe sepsis/septic...

An unusual finding of obstructive jaundice—a case report and review of the literature

Biliary ascariasis is a tropical infectious disease, endemic in regions such as the Far East, Indian subcontinent and parts of the Middle East. The responsible organism is the Ascaris lumbricoides worm. This case study presents a 54-year-old British Caucasian female patient, admitted with a 1-week history of generalized abdominal pain. Ultrasound scan of the abdomen showed a...

A case of a Müllerian cyst arising in the posterior mediastinum

A mediastinal Müllerian cyst is composed of heterotopic cystic Müllerian tissue resembling structures of the fallopian tube. We herein report a case of a mediastinal Müllerian cyst discovered during a medical check-up of a 41-year-old woman. She had no symptoms but had been diagnosed with hyperprolactinemia at the age of 24 years, for which she received hormonal therapy for 3...

Delayed diagnosis of odontogenic infection: a lesson from altered mental status and abnormal breathing

Altered mental status is a common, yet challenging, clinical presentation encountered by physicians. Here, we report a case of a 68-year-old Japanese female who was transferred to the emergency department due to faint. The laboratory results showed hyponatremia, ketonuria, hyperglycemia and acute kidney injury without fever or inflammatory findings. Although these abnormalities...

Purtscher-like retinopathy with serous macular detachment in pre-eclampsia

Purtscher-like retinopathy has been rarely described during postpartum period in patients with pre-eclampsia. We present an unusual combination of serous macular detachment coexisting with Purtscher-like retinopathy as a complication of pre-eclampsia during postpartum period.

Epidermal growth factor receptor mutated oligometastatic adeno-squamous lung cancer transformation to small cell lung cancer

A 66-year-old non-smoker was diagnosed with stage IIIB, epidermal growth factor receptor (EGFR) mutated, squamous cell lung carcinoma. Treatment included chemotherapy, 35 fractions of radiotherapy and later Gefitinib for 3.5 years. On progression he developed a solitary brain and liver lesion. The brain lesion was excised and histology revealed adenocarcinoma of a lung primary...

Atrial septal defect can be easily missed in chromosome 18q deletion syndrome

The frequency of 18q− is estimated to be approximately 1/40 000 live births and is more commonly associated with certain clinical features including short stature, intellectual disability and malformations of many major organ systems. Congenital cardiac abnormalities are present in 24–36% of cases and screening can prove difficult. A 28-year-old Caucasian female with a history of...

Omphalocele and epigastric heteropagus: implications and treatment

In heteropagus twins, the parasitic twin is incompletely formed which is attached to the autosite. We report a case of epigastric heteropagus twins with omphalocele. The parasite had two lower limbs, a rudimentary upper limb, genitalia with developed phallus and scrotum but absent testis. An omphalocele was present just below the attachment of the parasitic twin. A single kidney...

Acute kidney injury in a Tanzanian boy following multiple bee stings in resource-limited setting: a case report

Bee sting has been identified as among causative agents of nephrotoxic acute tubular necrosis which may lead to acute kidney injury. Bee envenomation has medicinal properties but when a higher dose is inoculated may cause severe anaphylaxis with very poor prognosis. We report a 12-year-old boy with acute kidney injury following multiple bee stings who recovered well after...

A 32-year-old man with hypoxemia and bilateral upper-lobe predominant ground-glass infiltrates on chest imaging

Diffuse alveolar hemorrhage (DAH) is a rare, but potentially fatal, complication of antiphospholipid syndrome, and may present with acute and fulminant symptoms. We report a case of DAH presenting as sudden onset dyspnea in a gentleman with known antiphospholipid syndrome. Chest computed tomography angiography with pulmonary embolism protocol showed right lower lobe segmental...

Asymptomatic hepatosplenomegaly in chronic myeloid leukemia

A 39-year-old male diagnosed as chronic myeloid leukemia, had no abdominal symptoms. However, his physical examination revealed apparent abdominal fullness. His liver and spleen were palpable. His abdominal CT revealed that a narrow space to pass intestinal digestive contents. Asymptomatic hepatosplenomegaly is somewhat typical in these chronic type hematological diseases.

Multi-system bleeding risk with a cutaneous angiosarcoma at an arteriovenous fistula site

We present a case of angiosarcoma at an arteriovenous fistula site in a non-immunocompromised patient presenting as a soft tissue swelling with associated findings suggestive of lung malignancy, metastases and bleeding diathesis. This patient died of an otherwise unexplained subdural haematoma. Given the ability of this tumour to metastasise early and the poor prognosis of...

Pseudomyxoma pleurii and peritonei secondary to sigmoid colon adenocarcinoma: a rare clinico-pathologico-radiological presentation

Pseudomyxoma peritonei (PMP) is a rare condition resulting from mucin-producing tumors that have disseminated into intraperitoneal implants and mucinous ascites. The extra-abdominal spread of PMP is exceptionally rare, with few reported cases in the medical literature. Pseudomyxoma pleurii is an infrequently encountered clinical syndrome characterized by transdiaphragmatic...

Variation of the PR interval for confirming ventricular pre-excitation on a 12-lead ECG

We present the case of a 14-year-old female patient with recurrent episodes of paroxysmal supraventricular tachycardia (PSVT). Her ECG showed a PR interval of 160 ms in lead II, and a delta wave pattern in leads V2 and V3, with a normal QRS interval of 100 ms. We analyzed the three criteria for confirmation of minimal pre-excitation: (i) absence of a Q wave in V6; (ii) presence...

Swinging heart caused by diffuse large B-cell lymphoma

Pericardial disease is a common complication of solid tumors and occasionally seen in hematologic malignancies. Pericardial effusion, when it occurs, is usually caused by tumor seeding of the pericardium leading to a serous effusion or by mass effect from mediastinal lymphadenopathy blocking drainage of lymphatic ducts. Pericardial disease from non-Hodgkin’s lymphoma is uncommon...

Rectal ischemia causes mass formation, masquerading as rectal cancer

Rectal ischemia rarely occurs because of the rich vascular supply of the rectum, while endoscopic presentation of ischemic colitis always is not distinct and can uncommonly mimic malignant neoplasm. We present a case of a rectal ischemia, which presented with haematochezia and proctoscopy revealed a large ulcerating mass, masquerading as rectal cancer and obstructed the lumen of...

Francisella tularensis bacteraemia causing multi-organ failure

Tularemia is a zoonosis caused by the gram-negative coccobacillus Francisella tularensis. The bacterium can be transmitted in several ways including direct contact with animal reservoirs, ingestion, inhalation and bites, and typical clinical symptoms are headache, fever, diarrhea and dyspnea. Francisella tularensis has two predominant subspecies (ssp), namely ssp. tularensis and...
