Varia genera morborum haemorrhagicorum sunt, quae praecipue secundum aetiologiam et pathogenesin clinicē digeruntur. Dividi possunt in vascularia, thrombocytaria, anomalias factorum coagulationis, et cetera.
1. Vasculare:
(1) Hereditarius: telangiectasia hereditaria, haemophilia vascularis, et textus sustentans abnormalis circa vasa sanguinea;
(2) Acquisita: laesio parietis vascularis causata a purpura allergica, purpura simplici, purpura medicamentis inducta, purpura aetate relata, purpura autoimmuni, infectione, factoribus metabolicis, factoribus chemicis, factoribus mechanicis, etc.

2. Proprietates thrombocytorum:
(1) Thrombocytopenia: thrombocytopenia immunis, thrombocytopenia medicamentis inducta, anaemia aplastica, infiltratio tumoris, leucaemia, morbi immunes, CID, hyperfunctio splenica, purpura thrombotica thrombocytopenica, etc.;
(2) Thrombocytosis: Thrombocytosis primaria, polycythaemia vera, splenectomia, tumor, dysfunctio thrombocytaria inflammatoria, thrombocytopenia, syndroma thrombocytariorum gigantum, morbus hepaticus, et dysfunctio thrombocytaria ab uraemia causata.

3. Factores coagulationis abnormales:
(1) Anomaliae hereditariae factorum coagulationis: haemophilia A, haemophilia B, defectus FXI, FV, FXI, FVII, FVIII, fibrinogeni congeniti humilis (absens), defectus prothrombini, et defectus factorum coagulationis complexorum;
(2) Anomaliae factorum coagulationis acquisitae: morbus hepaticus, defectus vitaminae K, leucaemia acuta, lymphoma, morbus textus connectivi, etc.

4. Hyperfibrinolysis:
(1) Primaria: Defectus hereditarius inhibitorum fibrinolyticorum vel aucta activitas plasminogeni facile hyperfibrinolysim in morbis hepaticis gravibus, tumoribus, chirurgiae et traumatibus inducere potest;
(2) Acquisita: visibilis in thrombosi, DIC, et morbo hepatico gravi (secundario)

Incrementum pathologicum substantiarum circulantium, inhibitores acquisiti ut F VIII, FX, F XI, et F XII, morbi autoimmunes, tumores maligni, gradus aucti anticoagulantium heparino similium, et anticoagulantium lupici.
