Summary
Agminated Spitz nevi, typically rare, can manifest during pregnancy. This case highlights an unusual occurrence of Spitz nevi appearing and spreading during gestation.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Spitz nevi are usually solitary, benign skin lesions.
- Agminated or disseminated Spitz nevi are uncommon presentations.
- Pregnancy can influence various dermatological conditions.
Observation:
- A pregnant patient presented with an unusual eruption of Spitz nevi.
- The nevi appeared and disseminated during the course of the pregnancy.
- This presentation is atypical for Spitz nevi.
Findings:
- The case demonstrates a rare instance of Spitz nevus dissemination.
- Pregnancy-associated hormonal changes may play a role in nevus development.
- Histopathological confirmation is crucial for diagnosis.
Implications:
- This case expands the understanding of Spitz nevus behavior.
- It highlights the importance of considering pregnancy in dermatological diagnoses.
- Further research is needed to explore the link between pregnancy and Spitz nevi.

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:20Proliferative Phase
The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
