In an attempt to delineate the spectrum of breast diseases in Saudi Arab females, we carried out a retrospective study of all cases of breast biopsies and mastectomies accessioned in the files of surgical pathology in our laboratory for 26 years (1967-1992). A total of 915 cases were collected. Fibroadenoma was the most common lesion encountered (30.7%), followed by fibrocystic condition (21.1%), carcinoma (14.9%), acute mastitis (7.2%), duct ectasia (4.9%), lactational adenoma (4.8%), intraductal papilloma (2.6%), galactocele (2.4%) and several less frequent lesions. Pathological conditions associated with lactation such as acute mastitis, abscess, granulomatous mastitis, galactocele and lactational adenomas constituted 16.2% of the cases in this series. This high frequency is related to the high fertility rate among Saudi Arab females. The mean age of Saudi Arab females with ductal carcinoma was 47.1 years as compared to 54 years in Western countries. Many patients presented with a large size tumor, skin and/or nipple involvement, as well as a high frequency (61.7%) of axillary nodal metastases in those who underwent axillary nodal dissection. The high frequency of fibroadenoma could be related to the large number of young females in our population. A great increase in the number of cases in the last five years has been observed. This could be related to more awareness among Saudi Arab females of their health problems and the expansion of our medical services.

Breast metastases from extra-mammary malignancies, especially those mimicking primary inflammatory breast carcinoma, are extremely rare. We report here two cases of inflammatory breast metastases from gastric or ovarian cancer. Both patients, who had prior advanced malignant disease, presented with unilateral breast redness and swelling with peau d'orange sign, resembling primary inflammatory breast cancer or acute mastitis. Breast biopsy revealed poorly differentiated adenocarcinoma with signet-ring cells or clear cell carcinoma in the lymphatic vessels and the parenchyma without an in situ lesion, similar to primary lesions of the stomach or ovary, respectively. Immunohistochemical staining for estrogen receptor, progesterone receptor, and gross cystic disease fluid protein 15 was of value for correct diagnosis. Since breast metastasis is a sign of poor prognosis of the primary malignant disease, the possibility of breast metastasis should be considered in appropriate patients to preclude unnecessary major surgery.

Regressive changes (RC) have been described in malignant melanoma, carcinomas of the prostate and cervix. The presence of RC in these neoplasms may signify some degree of host response to tumor and seems to be a sign of poor prognosis for some neoplasms. RC in breast cancer is vaguely defined in the older literature. We have observed periodically similar RC in a subset of high-grade ductal carcinoma in situ (HGDCIS) in breast specimens. The aim of our study is to demonstrate how to recognize RC in the diagnostic setting and an attempt to understand the biologic behavior in this subset of HGDCIS cases. Fifty-nine cases of HG-DCIS (35 cases with RC and 24 cases without RC) were included. We defined RC in our study as demonstrating thick periductal fibrosis, dense lymphocytic infiltrate, and a thin rim of intact neoplastic cells. A short panel of immunomarkers to study this entity included myoepithelial markers. Reduced expression of myoepithelial markers (p63 and smooth muscle heavy chain myosin) were seen more frequently in the HGDCIS group with RC than without RC cases. Invasion as well as metastatic disease was seen in association with HGDCIS with RC nearly 4 times as often. It is also critically important to recognize HGDCIS-RC for diagnostic purposes, as the differential diagnosis of RC includes, benign associations such as papilloma, fibrocystic changes and periductal mastitis. HGDCIS-RC may also be a sign of an aggressive phenotype than other HGDCIS subtypes. Further outcome studies are necessary to determine if it has a clinical impact akin to other tumors with RC.

A 42-year-old woman presented with localized irritation, erythema and sharp pain in the one breast. After unsuccessful treatment for mastitis, an oncology consultation was obtained. A breast biopsy revealed an invasive carcinoma and a diagnosis of inflammatory breast cancer was made. The patient was treated with neo-adjuvant chemotherapy and subsequently underwent bilateral mastectomy. A total abdominal hysterectomy and bilateral salpingo-oophorectomy was also performed at the same time due to the presence of a pelvic mass. Morphologic and immunohistochemical examination of the specimens helped to clarify the correct diagnosis of primary ovarian carcinoma with widespread metastases to bilateral breasts.

Inflammatory breast cancer (IBC) is a rare and aggressive form of invasive breast cancer accounting for 2.5% of all breast cancer cases. It is characterized by rapid progression, local and distant metastases, younger age of onset, and lower overall survival compared with other breast cancers. Historically, IBC is a lethal disease with less than a 5% survival rate beyond 5 years when treated with surgery or radiation therapy. Because of its rarity, IBC is often misdiagnosed as mastitis or generalized dermatitis. This review examines IBC's unique clinical presentation, pathology, epidemiology, imaging, and biology and details current multidisciplinary management of the disease, which comprises systemic therapy, surgery, and radiation therapy.

Breast MRI should not be used for differential diagnosis between inflammatory breast cancer and acute mastitis (AM) prior to treatment. When mastitis symptoms persist after 10 to 15 days of well-managed medical treatment, MRI may be performed in addition to an ultrasound examination, a mammogram and to taking histological samples, in order to eliminate inflammatory breast cancer (IBC). For staging, MRI would seem to be useful in looking for a contralateral lesion, PET-CT for finding information about remote metastases and in certain centres, for information about the initial extension to local/regional lymph nodes, which would guide the fields of irradiation (since patients can become lymph node negative after neoadjuvant chemotherapy). MRI and PET-CT seems to be useful for early detection of patients responding poorly to neoadjuvant chemotherapy so that the latter may be rapidly modified.

Cutaneous metastases can have many different clinical presentations. They are seen in patients with advanced malignant disease; however, they can be the initial manifestation of undetected malignancies. Inflammatory breast carcinoma is a rare and aggressive form of breast cancer that has a nonspecific appearance mimicking many benign conditions including mastitis, breast abscesses, and/or dermatitis. The authors report the case of a 40-year-old woman with inflammatory breast carcinoma presenting with violaceous papulovesicular lesions resembling lymphangioma circumscriptum and erythematous patches resembling erysipelas. These lesions represent two different types of cutaneous metastases, both of which were the initial signs of inflammatory breast carcinoma in the patient described herein. Skin biopsy of lesions confirmed invasive breast cancer and further prompted a work up for inflammatory breast carcinoma. This case demonstrates the importance of follow-up for all breast lesions, even those considered to be of benign nature, for they can be presenting signs of metastatic breast cancer.

A 56-year-old male patient with papillary thyroid carcinoma was given radioiodine for the treatment of persistent disease. Post radioiodine whole body scan revealed uptake at the thyroidal region and bilateral uptake at the upper thoracic region. Single photon emission computed tomography/computed tomography (SPECT/CT) confirmed uptake at the left thyroid lobe, and additional symmetrical mammary gland uptake was observed at both breasts. The patient had obesity-related gynecomastia, but he did not have any history of breast cancer, mastitis, hyperprolactinemia, or galactorrhea. Although breast uptake of radioiodine is a common finding in postpartum or lactating women, it is uncommon in male patients. To our knowledge, this is the first case of a male patient with breast uptake of radioiodine documented with SPECT/CT. SPECT/CT is useful in male patients in the differentiation of benign breast uptake with lung metastases or axillary metastases of thyroid cancer.

Cancer in the dermis of the breast has a poor prognosis. The breast dermis can become malignantly involved primarily in inflammatory breast cancer, through the direct extension of locally advanced breast cancer, or metastatically from an underlying breast mass or a distant primary malignancy (e.g., gastric adenocarcinoma). Breast dermal metastases have the shortest median survival among them. Breast dermal metastases are classified into eight clinicohistopathologic groups, one of which is carcinoma en cuirasse. We present a case of a 52-year-old female with a history of invasive ductal carcinoma, Stage IIIC (pT2N3a), treated with lumpectomy, axillary node dissection, and chemoradiation therapy that recurred as carcinoma en cuirasse breast dermal metastases. Through 18F-fludeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) and clinical images, the case illustrates the rapid progression and devastating consequences of carcinoma en cuirasse breast dermal metastases over a 4-month period despite optimal therapy. Furthermore, the case emphasizes the sensitivity of 18F-FDG PET-CT to detect pathology in the breast dermis. Finally, the case highlights the crucial role that nuclear medicine physicians play in helping clinical colleagues differentiate between the various breast dermal malignant manifestations and benign mastitis, a common confounder in postradiation patients.
