Breast carcinoma is the most common cancer in women. Nineteen different subtypes of breast carcinomas are recognized in the current WHO classification of breast tumors. Except for these subtypes, there are a number of carcinomas with special morphologic and immunohistochemical features that are not included in the 5th WHO classification, while others are considered special morphologic patterns of invasive breast carcinoma of no special type.

Article Synopsis
  • - The study investigates how the number of allergens a person is sensitized to (monosensitized vs polysensitized) affects the severity and variety of symptoms in patients with allergic rhinitis (AR).
  • - Results show that polysensitized patients reported more symptoms, especially itchy eyes and wheezing, compared to monosensitized patients, indicating that having multiple sensitivities leads to a greater symptom burden.
  • - The research concludes that greater sensitization correlates with a wider range of symptoms and suggests that different levels of sensitization may affect various organs in the body.

Article Synopsis
  • - The manuscript provides a systematic review of malignant Brenner tumors, which are uncommon ovarian tumors comprising less than 1% of all malignant ovarian neoplasms.
  • - A total of 48 studies were analyzed, encompassing 115 cases from the English literature, focusing on various patient characteristics and outcomes.
  • - Findings indicated that tumor stage, presence of ascites, and abnormal CA-125 levels were linked to recurrence, while lymphadenectomy was associated with improved disease-specific survival.

Background: Axillary lymph node metastasis is a rare stage IV ovarian carcinoma manifestation. This manuscript aims to systematically review the literature regarding axillary lymph node metastasis from ovarian carcinoma.

Methods: We searched three medical internet databases (PubMed, Scopus, and Web of Science) for relevant articles published until 22 July 2023.

Introduction: Breast cancer affects almost 1.5 million women worldwide below the age of 45 years each year. Many of these women will be advised to undergo adjuvant chemotherapy to minimize the risk of death or recurrence of the tumor.

Higher mammographic breast density in premenopausal and postmenopausal women is related to a higher breast cancer risk. In this review, we analyze the correlation between estrogen, progesterone, and mammographic density in postmenopausal women and clarify whether these findings are consistent across different types of mammographic breast density. We extracted data concerning mammographic density increases in the populations treated with estrogen-only hormone replacement therapy and those treated with estrogen and progestin hormone replacement therapy.

Prostatic adenocarcinoma (PA) is the second most common malignancy in men globally. Signet-ring cell-like adenocarcinoma (SRCC) is a very rare PA subtype, with around 200 cases reported in the English literature. Histologically, the tumor cells show a vacuole compressing the nucleus to the periphery.

Ectopic or accessory breast tissue may occur in primitive embryonic milk lines or locations other than the milk line. The same pathology arising in breast tissue may occur less frequently in ectopic breast tissue. Fibroadenomas rarely occur in ectopic breast tissue, with less than 50 reported cases in the English literature, despite being the most common benign breast neoplasms.

Mammary myofibroblastoma is a benign mesenchymal tumor composed of fibroblasts, myofibroblasts, and a variable number of adipocytes. Mammary myofibroblastoma usually occurs in men of older age and is less common in postmenopausal women. It may also happen in extramammary sites along the milk line.

Leiomyomas are the most common benign smooth muscle tumors of the female genital tract. Among the recognized histologic variants, one of the least common is plexiform leiomyoma. When they are small, even microscopic findings, they are referred to as plexiform tumorlets.

Background/aim: Utilizing an experimental animal model, we investigated the correlation between aromatase inhibitors (AIs) (anastrozole and letrozole) and Calprotectin levels. AIs have demonstrated superior efficacy when used as adjuvant endocrine therapy or monotherapy for postmenopausal patients with hormone receptor (HR)-positive early-stage breast cancer, although various side effects have been recorded.

Materials And Methods: Fifty-five adult female Wistar rats were randomized and assigned into four groups.

The objective of the present systematic review was the determination of methodologies preferable for treating phyllodes tumors (PTs) of the breast and whether the malignancy of the tumor is of significance to the selected treatment. In addition, to investigate if local recurrence (LR) within patients is different based on the therapeutic approach followed by the physician. All studies were gathered by utilization of the biggest online medical databases in the world including PubMed, Cochrane, Embase, Web of Science and Google Scholar.

Background: Angiogenesis is a hallmark of breast cancer (BC) and is mediated by the vascular endothelial growth factor (VEGF) signaling axis. It is regulated by different proangiogenic factors, including platelet-derived growth factor-CC (PDGF-CC) and heparin-binding EGF-like growth factor (HB-EGF), as well as co-receptors, such as neuropilin-1, which could have prognostic implications in BC patients.

Patients And Methods: We assessed the serum levels of VEGF, HB-EGF, PDGF-CC and neuropilin-1 in 205 patients with early BC (invasive, = 187; in situ, = 18) and in 31 healthy donors (HD) and investigated the potential associations with clinical and histopathological parameters.

Microglandular adenosis is a non-lobulocentric haphazard proliferation of small round glands composed of a single layer of flat to cuboidal epithelial cells. The glandular structures lack a myoepithelial layer; however, they are surrounded by a basement membrane. Its clinical course is benign, when it is not associated with invasive carcinoma.

Dermatofibrosarcoma protuberans (DFSP) is a superficial mesenchymal neoplasm that originates from the dermal fibroblasts and tends to be locally aggressive. Although infrequent, it is one of the most common cutaneous sarcomas. It mainly affects young and middle-aged patients 20 to 50 years old.

Matrix-producing carcinoma (MPC) is a rare subtype of metaplastic breast carcinoma (MBC) that was first described in 1989 by Wargotz and Norris. It accounts for less than 1% of breast carcinomas and has distinctive clinical, morphological, and immunohistochemical features. Histologically it consists of invasive carcinoma of no special type with transition to cartilaginous or osseous matrix without a spindle cell component.

Pulmonary actinomycosis is a rare infectious disease, which is characterized by a wide range of symptoms and no specific imaging findings and may be confused with neoplasia, tuberculosis or pneumonia. Endobronchial involvement of actinomycosis may be caused by aspiration of foreign bodies or broncholithiasis and may bronchoscopically masquerade as malignancy. A case of 68-year-old man is reported, who presented with productive cough and fever and had no response to antibiotic therapy with moxifloxacin.

Background/aim: Studies have focused on heat shock protein (Hsp) inhibitors as potential treatment agents in breast cancer, with controversial results. Adopting a pathophysiological perspective, this systematic review aims to synthesize the evidence examining the association between Hsp70/Hsp90 expression and breast cancer prognosis, as well as prognosis-related clinicopathological indices. Secondarily, changes in Hsp70/Hsp90 expression in the continuum of breast neoplasia were assessed.
