Background: Plasma lipoprotein(a) (Lp[a]) concentrations are primarily determined by genetic factors and are believed to remain stable throughout life. However, data are scarce on longitudinal trends in Lp(a) concentrations over time. Therefore, it is unclear whether measurement of Lp(a) once in a person's life is sufficient for cardiovascular risk assessment in all adults.
Methods and Results: Lp(a) concentrations, specifically apolipoprotein(a) concentrations, were measured at visits 4 and 5, ≈15 years apart, in 4734 adult participants of the ARIC (Atherosclerosis Risk in Communities) study (mean age at visits 4 and 5, 60.7±5.1 and 75.5±5.2 years, respectively). Participants were categorized by baseline …

Blastic plasmacytoid dendritic cell neoplasm usually presents as skin lesions. Diagnostic error occurs when it primarily presents in leukemic phase without skin involvement. Triad of CD4, CD56 and CD123 immunophenotype expression is essential to avoid misdiagnosis of this rare hematological malignancy. Here we describe a patient who presented in overt leukemic phase of BPDCN highlighting diagnostic challenges encountered that resulted in delayed diagnosis and poor outcome

Solitary fibrous tumour (SFT) is a ubiquitous benign mesenchymal tumour of fibroblastic origin, which occurs most often in middle-aged adults. It usually presents as lung mass originating from pleura, but extrapleural occurrence is also common. Tumour is characterised by hypo- and hyper-cellular areas of spindle-shaped cells, arranged in haphazard manner with dispersed staghorn-shaped vessels. Surgical excision is the curative treatment. SFTs of the primary testicular or paratesticular region are extremely rare, but they exhibit histologic findings similar to SFTs originating at other body sites. Here, we report the case of a paratesticular SFT in a 37-year male, who presented with …

Chronic granulomatous inflammation is a common finding in lymphoproliferative disorders (LPDs), but it is important to exclude coexisting mycobacterium tuberculosis (MTB) especially in patients from areas of high endemicity. This case emphasizes the relevance of performing MTB culture on bone marrow exhibiting LPD and concomitant granulomas

Objective: To determine the accuracy and false negative rate of axillary ultrasound compared to sentinel node biopsy.
Methods: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, from February 1 to March 31, 2021, and comprised data of breast cancer patients who had undergone neo-adjuvant chemotherapy followed by axillary lymph node dissection or axillary disease diagnosed using lymph node biopsy or sentinel lymph node biopsy between January 1, 2016, and December 30, 2020. After receiving neoadjuvant chemotherapy, axillary ultrasound findings were compared with histopathology of lymph nodes. Data was analysed using SPSS 22.
Results: Of the 155 …
