Specialty | Endocrinology |
Sulfatidosis is a form of lysosomal storage disease resulting in a proliferation of sulfatide.
It is caused by a genetic insufficiency of sulfatase enzymes. [1]
Metachromatic leukodystrophy and multiple sulfatase deficiency are classified as sulfatidoses. [2] [3]

Lisch nodule, also known as iris hamartoma, is a pigmented hamartomatous nodular aggregate of dendritic melanocytes affecting the iris, named after Austrian ophthalmologist Karl Lisch (1907–1999), who first recognized them in 1937.
Dactylitis or sausage digit is inflammation of an entire digit, and can be painful.
Angiomas are benign tumors derived from cells of the vascular or lymphatic vessel walls (endothelium) or derived from cells of the tissues surrounding these vessels.
Erythema induratum is a panniculitis on the calves. It occurs mainly in women, but it is very rare now. Historically, when it has occurred, it has often been concomitant with cutaneous tuberculosis, and it was formerly thought to be always a reaction to the TB bacteria. It is now considered a panniculitis that is not associated with just a single defined pathogen. The medical eponym Bazin disease was historically synonymous, but it applies only to the tuberculous form and is dated.
Left shift or blood shift is an increase in the number of immature cell types among the blood cells in a sample of blood. Many clinical mentions of left shift refer to the white blood cell lineage, particularly neutrophil-precursor band cells, thus signifying bandemia. Less commonly, left shift may also refer to a similar phenomenon in the red blood cell lineage in severe anemia, when increased reticulocytes and immature erythrocyte-precursor cells appear in the peripheral circulation.
A thyroid adenoma is a benign tumor of the thyroid gland, that may be inactive or active as a toxic adenoma.
In pathology, Anitschkowcells are often cells associated with rheumatic heart disease. Anitschkow cells are enlarged macrophages found within granulomas associated with the disease.
Obstructive uropathy is a structural or functional hindrance of normal urine flow, sometimes leading to renal dysfunction.
Acantholysis is the loss of intercellular connections, such as desmosomes, resulting in loss of cohesion between keratinocytes, seen in diseases such as pemphigus vulgaris. It is absent in bullous pemphigoid, making it useful for differential diagnosis.
Dyskeratosis is abnormal keratinization occurring prematurely within individual cells or groups of cells below the stratum granulosum.
Obstructive shock is a form of shock associated with physical obstruction of the great vessels or the heart itself. Pulmonary embolism and cardiac tamponade are considered forms of obstructive shock.
Spermatocytic tumor, previously called spermatocytic seminoma, is a neoplasm of the testis, and classified as a germ cell tumour.
Papillomatosis of skin is skin surface elevation caused by hyperplasia and enlargement of contiguous dermal papillae. These papillary projections of the epidermis form an undulating surface under microscopic examination.
Hydropic swelling is intracellular edema of keratinocytes, often seen with viral infections.
Exocytosis is infiltration of the epidermis by inflammatory or circulating blood cells.
Respiratory bronchiolitis interstitial lung disease refers to a form of idiopathic interstitial pneumonia associated with smoking.
CFU-Meg is a colony forming unit. Haematopoiesis in the bone marrow starts off from a haematopoietic stem cell (HSC) and this can differentiate into the myeloid and lymphoid cell lineages. In order to eventually produce a megakaryocyte, the haematopoietic stem cell must generate myeloid cells, so it becomes a common myeloid progenitor, CFU-GEMM. This in turn develops into CFU-Meg, which is the colony forming unit that leads to the production of megakaryocytes.
CFU-Baso is a colony forming unit. that gives rise to basophils. Some sources use the term "CFU-Bas".
CFU-Eo is a colony forming unit that gives rise to eosinophils. Some sources prefer the term "CFU-Eos". It is also known as "hEoP".
Nonthrombocytopenic purpura is a type of purpura not associated with thrombocytopenia.
