Sarcoidosis is a multi-system inflammatory disorder of unknown cause. Most patients with this disease present with respiratory symptoms as lungs are frequently affected organs. Symptomatic muscle involvement is rare1 and presentation of this disease as myopathy is even rarer.2 We describe a case of a lady who presented with severe disabling proximal myopathy as the only feature of underlying sa...

A technique for automating the detection of lymphocytes in histopathological images is presented. The proposed system takes Hematoxylin and Eosin (H&E) stained digital color images as input to identify lymphocytes. The process involves segmentation of cells from extracellular matrix, feature extraction, classification and overlap resolution. Extracellular matrix segmentation is a two step proce...

Colorectal masses can be non-neoplasm, benign neoplasm and malignant neoplasm. Diagnosis of colorectal mass done by biopsy or surgery then followed histopathological examination. The aim this study was to described the histopathology feature in Anatomic Pathology Laboratory Arifin Achmad Regional Hospital Riau Province January 2015 - December 2019. This found 304 cases consisted men (55,6%) wom...

Synchronous primary non-small cell lung cancers (NSCLC) are rare and may be discovered unexpectedly following lung resection. Discrimination from intrapulmonary metastases is important to guide treatment and prognosis but is difficult solely on clinical or radiological findings. Histopathological evaluation with immunohistochemistry (IHC) markers can prove decisive and should feature in the dia...

Primary bone lymphoma involving the pelvic bone is a rare entity. It does not have distinct clinical features or radiological features that are diagnostic. Biopsy is the gold standard investigation. We present a case of primary pelvic lymphoma with initial histopathological features of chronic osteomyelitis. Upon further clinical follow-up, repeat biopsy of the lesion revealed features of B-cel...

Lichen simplex chronicus is a skin disease that mostly affects female patients, with a peak incidence between ages 35 and 50 years. On the scalp, it appears as a single or multiple oval lesions, showing scaling and hair shaft loss or breakage. An important dermoscopic feature of the disease are the “broom fibers.” Histopathology reveals the “hamburger” and the “gear wheel” signs. The aim of thi...

Ganglioneuromas, benign tumors of the sympathetic nervous system, are rare to arise in the parapharyngeal space. They are usually asymptomatic and hormonally silent. The interest of this case lay in the rarity of its incidence at the pharyngeal space. Majority of cases are detected incidentally during work-up for unrelated conditions. They usually develop from the great sympathetic chains, exte...

in this paper, the performance of 11 different distances for image retrieval and classification, based on color, shape and texture, is evaluated. the precision-recall measure and the correct classification rate of the k-nn classifier are used to evaluate retrieval and classification performances, respectively. the experimental results for a database of 1000 images from 10 different semantic gro...
