Clinical And Pathological Features

Colonization of breast carcinoma by non-neoplastic melanocytes of epidermal origin was first described by Azzopardi and Eusebi in 1977. We herein report two cases on the exceptional clinical and pathological features of this phenomenon in a 66-year-old and a 51-year-old patients. The pathogenesis is not fully understood, but a disrupted basement membrane and the role of tumoral growth factors are considered essential.

Clinical And Pathological Features

Introduction. Melanocyte colonization of breast carcinoma by nonneoplastic melanocytes of epidermal origin is a rare and serious condition first described in 1977. We report on the exceptional clinical and pathological features of this migration phenomenon in a 74-year-old patient.Discussion. The pathogenesis by which melanocyte migration takes place is not known, but a breached basement membrane is considered essential.Conclusion. Histological examination and additional staining of skin are essential to differentiate breast cancer melanosis from malignant melanoma.

Clinical And Pathological Features

Background: Invasive breast cancer (IBC) can be categorized into prognostic and predictive molecular subtypes (including luminal breast cancer) using gene expression profiling. Luminal IBC comprises a variety of histological subtypes with varying clinical and pathological features. Summary: IBC of no special subtype is the most common histological subtype in general and likewise within luminal IBC. Classical invasive lobular breast cancer, typically clustering into luminal subgroup, is characterized by discohesive growth and loss of E-cadherin expression. Infrequent, morphologically distinct luminal IBC subtypes are tubular, invasive cribriform, mucinous, and invasive micropapillary carcinomas. Breast carcinoma with apocrine differentiation, with characteristic expression of androgen receptor (AR), often clusters into the luminal AR category. Rarely, neuroendocrine neoplasms of the breast can be seen. IBC of the male breast usually matches with the luminal subtype. Key Messages: Independently from histological subtypes, invasive breast cancer (IBC) can be divided into molecular subtypes based on mRNA gene expression levels. Using this molecular subtyping, risk scores based on gene expression profiling (established for hormone receptor-positive, HER2-negative IBC), grading, and Ki-67 index, prognosis of patients with luminal breast cancer and response to chemotherapy can be predicted. In routine diagnostics, the expression of estrogen receptor (ER) and progesterone receptor (PR), HER2 status, and the proliferation rate (Ki-67) are used to determine a surrogate (molecular-like) subtype. Within luminal(-like) IBC, no special subtype and invasive lobular breast carcinoma are the most common histological subtypes. Other rare histological subtypes (e.g., tubular carcinoma) should be recognized due to their distinct clinical and pathological features.

Clinical And Pathological Features

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term “cannabis arteritis” should be avoided until or unless more convincing scientific support is forthcoming.
