ASAP, generally, is not considered a pre-malignancy, or a carcinoma in situ; it is an expression of diagnostic uncertainty, [1] and analogous to the diagnosis of ASCUS (atypical squamous cells of undetermined significance) on the Pap test.
An ascus (from Ancient Greek ἀσκός (askós) 'skin bag, wineskin'; pl.: asci) [1] is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division.
Euamyloid and KOH-pretreated hemiamyloid structures react blue regardless of the type of iodine reagent. Hemiamyloid and euamyloid reactions may occur at a time, either at spatially separated sites of the cell wall (e.g., ascus apical ring euamyloid, lateral wall hemiamyloid), or as an intermediate type of the same wall region.
The ascus itself forms as a radiating spur branch at the top of the hook. Each nucleus divides, resulting in the formation of a pair of compatible nuclei, i.e. a dikaryon, in the ascus, which is now the penultimate space. Two sister nuclei remain, one in the basal cell and the other in the crozier tip.

Does a patient’s appearance at a doctor’s appointment impact the way their health care provider treats them? It’s a worry some people have, and as it turns out, there’s some merit to it.
Sexual reproduction in the Ascomycota leads to the formation of the ascus, the structure that defines this fungal group and distinguishes it from other fungal phyla. The ascus is a tube-shaped vessel, a meiosporangium, which contains the sexual spores produced by meiosis and which are called ascospores.
Newly diagnosed patients often feel cut off from family and friends, says the National Cancer Institute, the agency that guides U.S. research into the disease. Relationships change as loved ones ...
