Malignant hypercalcemia revealing a diffuse large B-cell lymphoma in a patient with a previous diagnosis of chronic myelomonocytic leukemia: An uncommon hematological coexistence.

A 76-year-old patient previously admitted to the cardiology department for replacement of a right ventricular lead on a double-chamber pacemaker was admitted to the internal medicine department 15 days after for bronchopneumopathy. His past medical history was relevant for Type 2 diabetes mellitus, heart failure due to dilated hypokinetic heart disease, transcatheter aortic valve implantation (TAVI), and chronic myelomonocytic leukemia (CMML-0) diagnosed in 2021. Twenty-four hours after admission, the patient's general condition deteriorated abruptly, with the onset of drowsiness and psychomotor retardation. Laboratory exams revealed hypercalcemia at 4.18 mmol/L. Intensive hydration, calcitonin, and zoledronic acid were initiated and the patient was transferred to the nephrology intensive care unit where he underwent two sessions of hemodialysis to normalize serum calcium levels before readmission to internal medicine. Laboratory exams revealed low parathyroid hormone, normal 1-25-OH vitamin D, and increased parathyroid hormone-related peptide. Thoracoabdominal and positron emission tomography (PET) scan showed diffuse abdominopelvic peritoneal carcinosis associated with low-grade pleural effusion and multiple supra- and sub-diaphragmatic adenopathies, leading to a search for a solid tumor. The patient's clinical condition worsened leading to a transfer to the intensive care unit. The biopsy of a peritoneal carcinosis nodule confirmed the diagnosis of diffuse large B-cell lymphoma. Specific treatments were unsuccessful and the patient expired.

Focal Myositis of the Sternocleidomastoid Muscle: A Rare and Uncommon Cause of Cervical Mass.

We report on a 70-year-old male patient admitted to the internal medicine department for evaluation of a right cervical mass. He had been treated with antibiotics as an outpatient by his primary care doctor. Upon admission the patient was asymptomatic, but within a few hours his cervical mass enlarged; this enlargement was confined to the right sternocleidomastoid muscle. Complete blood investigations including serology and autoimmunity were negative. The neck scan and MRI were in favour of myositis. No other lesions were found either in the nasal fibre-optic exam or in the thoracic-abdominal-pelvic scan. The biopsy of the muscle showed a lymphoplasmacytic inflammatory infiltrate of the perimysium. The diagnosis of focal myositis was made. The patient clinically improved during hospitalisation with complete resolution of symptoms without any specific intervention. LEARNING POINTS: A thorough clinical examination is essential in the evaluation and characterisation of cervical masses.The diagnostic approach must be rigorous in order not to ignore potentially serious diseases.A high level of clinical suspicion is needed in the diagnosis of focal myositis.

Idiopathic CD4+ T-cell Lymphocytopenia: Report of a Case 11 Years after Diagnosis.

We report the case of a 23-year-old woman evaluated for asthenia and lymphocytopenia. Clinical examination was unremarkable but laboratory tests showed the presence of CD4 lymphocytopenia. Secondary causes of CD4 lymphocytopenia were ruled out and a previous diagnosis of idiopathic CD4+ T-cell lymphocytopenia was retained. CD4 lymphocytopenia has persisted for 11 years now but the patient has been clinically asymptomatic. LEARNING POINTS: CD4+ T-cell lymphocytopenia needs to be meticulously evaluated and secondary causes ruled out.The patient has been clinically asymptomatic for 11 years.Measurement of CD4 subsets twice yearly seems to be appropriate.

Intellectual Disability, Falls and Gait Disturbances: A Misdiagnosis.

We report the case of a 27-year-old man presenting with slowly progressive extrapyramidal dysfunction and learning disability considered to have a syndromic intellectual disability. The re-evaluation of the clinical features and the investigations performed led to the diagnosis of atypical pantothenate kinase-associated neurodegeneration (PKAN). LEARNING POINTS: Patients with an intellectual disability should be carefully evaluated.In the evaluation of a patient with extrapyramidal dysfunction for several years, with gradual progression, spasticity and psychiatric disturbances, PKAN should be considered.

Tuberculosis as a Cause of Rapid Salivary Gland Swelling in the Elderly - A Case Report.

A 77-year-old man was admitted to the internal medicine department for a 5-day history of progressive preauricular swelling. Two lines of antibiotic treatment failed to achieve any improvement. Fine needle aspiration cytology was conducted and smear staining with the Ziehl-Neelsen stain as well as a PCR test were positive for Mycobacterium tuberculosis. These results were confirmed with culture of the sample. A diagnosis of tuberculosis parotitis was made and anti-tuberculous drugs were initiated. LEARNING POINTS: In patients not responding to usual antibiotic treatment, other rare causes of parotitis should be suspected.Fine needle aspiration cytology was an important procedure in establishing the diagnosis.

Anosmia and Dysgeusia in the Absence of Other Respiratory Diseases: Should COVID-19 Infection Be Considered?

We describe two elderly patients evaluated at emergency departments for anosmia/dysgeusia in the absence of any other respiratory symptoms prior to or upon admission. In the current epidemiological context, clinical and biological work-up led to a diagnosis of COVID-19 infection. Unfortunately, one of the patients died during hospitalization, but the other recovered and was discharged. LEARNING POINTS: In the current epidemiological situation, anosmia and dysgeusia in the absence of other respiratory conditions should be carefully evaluated.Special attention should be given to patients with non-classic COVID-19 symptoms in order to reduce transmission and protect health providers.
