BASIC TERMINOLOGIES AND DIFFERENT PATTERNS IN PATHOLOGY | UNDERSTANDING THE FOUNDATION OF REPORTING

BASIC TERMINOLOGIES AND DIFFERENT PATTERNS IN PATHOLOGY | UNDERSTANDING THE FOUNDATION OF REPORTING | A MUST WATCH FOR EVERY PATHOLOGIST ESPECIALLY THE POSTGRADUATES AND PATHOLOGY STUDENTS Schaumann body: Laminated calcified structure Seen in sarcoidosis but rare in skin lesions Sclerosis: Excess connective tissue with decreased amount of fibroblasts Shadow cells: Cells without a nucleus due to prior cell death Sinus: Tract connecting cavities to each other or to the surface Spongiform pustule of Kogoj: Collection of neutrophils within the stratum spinosum Associated with spongiosis at the periphery (e.g. seen in psoriasis) Seen in psoriasis, including pustular variants Spongiosis: Intraepidermal edema causing splaying apart of keratinocytes in stratum spinosum (resembling a sponge) Intercellular adhesion proteins (desmosomes) often visible Vesicles due to shearing of desmosomes Squamous eddies: Whorled profiles composed of keratinocytes (e.g. seen in inverted follicular keratoses) Storiform: Growth pattern consisting of spindle cells arranged in a cartwheel-like pattern Classically seen in dermatofibrosarcoma protuberans (DFSP) Telogen: Hair during resting phase Ulceration: Discontinuity of skin causing complete loss of epidermis and possible loss of dermis with accompanying surface fibrin deposition or exudate with or without granulation tissue response Verocay body: Structure composed of 2 nuclear palisades with central eosinophilic cytoplasmic processes Classically seen in schwannoma Vesicle Von Hansemann cells: Large macrophages containing Michaelis-Gutmann bodies seen in malakoplakia Wheal: Itchy, transient, elevated area with variable blanching and erythema Due to dermal edema #pathologyterminologies #PathologyPatterns #medicalterminology #DiseaseClassification #DiagnosticPatterns #PathologicalFeatures #CellularAbnormalities #TissuePatterns #Histopathology #cytology #bloodtests #MicroscopicExamination #GrossPathology #Immunohistochemistry #MolecularPathology #TumorMarkers #InflammatoryDiseases #InfectiousPathology #NeoplasticDisease #PathologyEducation
