Nodular melanoma (Created page with "'''Staining''': HE '''Organ''': Skin '''Description''': Like the name implies the tumor forms a nodule. The tumor cells are highly atypical, bordering on anaplastic. Some of the tumor cells contain melanin. Tumor cells are present in the epidermis as well. '''Diagnosis''': Nodular melanoma '''Causes''': * Sun exposure '''Theory''': The presence of tumor cells in the epidermis is essential to establish the diagnosis of ''primary'' melanoma. If there were no tumor...") Tag: Visual edit

Basal cell carcinoma (Created page with "'''Staining''': HE '''Organ''': Skin '''Description''': The tumor forms nests of tumor cells in the dermis. The tumor cells on the periphery of the nests line up in a special way. This phenomenon is called ''palisading''. Around the tumor nests small artefacts form. These ''retraction artefacts'' are due to the fixation and staining process of the sample, but it only occurs in basal cell carcinoma samples and is therefore characteristic for it. The tumor cells show...") Tag: Visual edit

Seborrhoeic keratosis (Created page with "'''Staining''': HE '''Organ''': Skin '''Description''': A well-circumscribed skin lesion is visible. The stratum corneum is thickened, meaning that there is ''hyperkeratosis''. The cells of the stratum corneum have retained their nuclei, meaning that there is ''parakeratosis''. There are neutrophils in the stratum corneum. These are not related to the disease and are instead the result of the patient scratching the seborrheic keratosis, causing irritation. The basa...")

Mucinous carcinoma (Created page with "''This slide is no longer part of the curriculum as of spring 2020, so you shouldn’t have to learn it.'' '''Staining''': HE '''Organ''': Breast '''Description''': The top of the slide shows normal breast tissue. The tumor is obvious. The tumor cells form clusters that are “floating in a sea of mucin”. These tumor cells have lost their orientation and therefore secrete mucin outwards instead of inwards (into an acinus) '''Diagnosis''': Mucinous carcinoma '''R...") Tag: Visual edit

Invasive ductal carcinoma (Created page with "'''Staining''': HE '''Organ''': Breast '''Description''': Normal breast tissue, including lots of adipose tissue, is visible on the left and right sides of the slide. In the middle is the invasive tumor. The tumor has a desmoplastic (fibrotic) neostroma, and the gland-like structures show mild atypia. DCIS, the precursor lesion of invasive ductal carcinoma, is also visible on the top of the slide. It’s a large, dilated duct that is filled with tumor cells. Its myoe...") Tag: Visual edit
