Breast Malignancy (breast + malignancy)
Selected AbstractsAspiration cytology of sarcomatoid carcinoma of the breast: Report of a case with cystic changeDIAGNOSTIC CYTOPATHOLOGY, Issue 1 2004Smita Mary Matthai MBBS Abstract Sarcomatoid/metaplastic carcinomas of the breast are rare breast malignancies that show a myriad of cytohistologic patterns in aspirates. These poorly differentiated invasive carcinomas contain both ductal and mesenchymal elements with transitional forms displaying either spindle, squamous, chondroid, or osseous differentiation. We describe such a neoplasm in a 68-yr-old woman, the diagnosis of which was missed at the initial fine-needle aspiration (FNA) due to cystic change. Extensive cystic change in a sarcomatoid carcinoma is unusual and is reported for the first time in the English literature. Diagn. Cytopathol. 2004;31:10,13. © 2004 Wiley-Liss, Inc. [source] Secondary breast cancer: a 5-year population-based study with review of the literatureAPMIS, Issue 10 2009TOR AUDUN KLINGEN Secondary tumours in the breast are rare. Based on literature, an incidence of 0.4,2% is reported. In this population-based study, secondary breast tumours from a 5-year period (2001,2005), not including metastasis from contralateral breast carcinoma, were reviewed (Vestfold County, Norway). A total of 722 patients with breast malignancies were found in this population (89.3% from Vestfold County Hospital). Ten of these, approximately 1.4%, were metastatic tumours, representing four cutaneous melanomas, three pulmonary carcinomas and three malignant lymphomas. The tumours were often solitary, palpable and close to the skin. Radiologically, the lesions mostly resembled primary carcinomas by mammography and ultrasound, which differs from other studies. Comparison with a known primary tumour and use of immunohistochemical profiling is of crucial importance. Melanoma markers (Melan-A, HMB-45, S-100 protein), lung cancer markers (Cytokeratins, TTF1, Chromogranin, Synapthophysin) and lymphoid markers (CD3, CD20) usually help to confirm a secondary breast tumour diagnosis. This approach is especially indicated in diffusely growing tumours with lack of glandular structure and high-grade cytological features, and staining for ER and GCDFP15 may be helpful. Thus, the diagnosis of a breast metastasis may be suspected by careful mammography and ultrasound imaging, although some cases have atypical radiological features, and histological examination might be necessary to ensure a correct diagnosis and appropriate treatment.

Carcinoma en cuirasse is a form of metastatic cutaneous breast malignancy occurring most commonly on the chest as a recurrence of breast cancer, but it can be the primary presentation. Objective. To discuss the clinical features of carcinoma en cuirasse that distinguish it from hypertrophic scars and keloids of the chest. Method. We report a 63-year-old woman with primary cutaneous breast carcinoma presenting as keloid nodules on the chest that failed treatments for keloids. Biopsy revealed a pattern of breast carcinoma in the skin. Results. After further workup, no tumor was found in the deep breast tissue, but metastases were found in her axillary lymph nodes. Conclusions. Unusual keloid-like nodules or scars on the chest that fail to respond to therapy may be primary or metastatic malignancies, and adequate histologic verification should be obtained to avoid delay in the proper treatment. [source] An unusual association of pemphigus vulgaris with hyperprolactinemiaINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2002MNAMS, Sujay Khandpur MD A 21-year-old unmarried woman presented with oral ulcerations and generalized, itchy, fluid-filled, skin lesions of 10 days' duration. The lesions ruptured spontaneously, resulting in extensive denuded areas covered by crusts. One month prior to this, she experienced pain and enlargement of both breasts with galactorrhea. Her menstrual cycles were normal initially, but later she developed menstrual irregularities. No past history suggestive of any other systemic or skin disease, including atopy or drug allergies, could be obtained. Her family history was not contributory. Dermatologic examination revealed multiple, flaccid bullae and extensive denuded areas of skin covered with crusts over the scalp, face, trunk, and upper and lower limbs (Fig. 1). Bulla spread sign and Nikolsky's sign were positive. The oral mucosa, including the lips, buccal surface, tongue, and palate, showed multiple erosions covered with necrotic slough. The rest of the mucocutaneous and systemic examination was within normal limits. Figure 1. Extensive erosions and flaccid bullae over the trunk with breast enlargement The patient's diagnostic work-up revealed: hemoglobin, 11.2 g%; total leukocyte count, 7400/mm3; differential leukocyte count, P62L34E2M2; erythrocyte sedimentation rate, 34 mm/h. A peripheral blood smear examination, urinalysis, blood sugar, and renal and liver function tests were normal. Venereal Disease Research Laboratory (VDRL) test and enzyme-linked immunoabsorbent assay (ELISA) for human immunodeficiency virus (HIV) were nonreactive. Antinuclear antibody, lupus erythematosus (LE) cell, rheumatoid factor, and anti-dsDNA levels were normal. Serum protein electrophoresis demonstrated increased levels of immunoglobulin G (IgG) antibody. The serum prolactin level was significantly raised to 139.49 ng/mL (normal, 3.6,18.9 ng/mL). The sex hormone levels, however, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and progesterone, were within normal limits. The thyroid hormone profile was also unaltered. Chest X-ray was normal. Ultrasound of the abdomen and pelvis revealed no visceral abnormality and computerized tomography (CT) scan of the pituitary sella showed no adenoma. Mammography was negative for breast malignancy. A Tzanck smear prepared from the base of the erosion showed multiple acantholytic cells and lymphocytes. Histologic examination from an intact vesicle was suggestive of pemphigus vulgaris (PV), showing a suprabasal cleft with acantholytic cells and the basal layer demonstrating a "row of tombstones" appearance (Fig. 2). Direct immunofluorescence (DIF) revealed the intercellular deposition of IgG and C3 throughout the epidermis in a "fishnet pattern." Indirect immunofluorescence (IIF) test performed on rat esophagus for circulating IgG antibody was positive in a titer of 1 : 120. Figure 2. Photomicrograph showing suprabasal cleft with "row of tombstones" appearance, suggestive of pemphigus vulgaris (hematoxylin and eosin, × 40) Based on the clinical and immunohistological features, a diagnosis of PV with idiopathic hyperprolactinemia was made. The patient was treated with bromocriptine mesylate (Tablet Proctinal, Glaxo Wellcome Ltd, India) at a dose of 2.5 mg twice a day. After 2 months of therapy, significant improvement in the skin lesions was observed. The existing lesions re-epithelialized with a drastic reduction in the number and distribution of new vesicles. However, no change in the mucosal erosions was noticed. IIF test demonstrated a lower antibody titer (1 : 40). The breast complaints also improved with a reduction in serum prolactin level to 6.5 ng/mL. The patient refused further treatment as she experienced nausea and dizziness with bromocriptine. After 2 weeks, the disease relapsed with the appearance of new vesicles over the forearms, abdomen, back, and thighs. She again complained of breast tenderness and galactorrhea, and the serum prolactin level was 95 ng/mL. The IgG titer increased to 1 : 120. Hence, treatment with oral prednisolone (2 mg/kg/day) and bromocriptine (2.5 mg twice a day) with an antiemetic was initiated. After 6 weeks, the skin lesions had cleared completely, the breast symptoms had improved, menses had become regular, and the prolactin level had decreased to 4 ng/mL. IIF test was negative for circulating antibody. Steroids were tapered off and maintenance therapy with bromocriptine at a dose of 2.5 mg/day was continued. [source] Clear Cell Hidradenocarcinoma Developing in Pacemaker PocketPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 11 2008CESAR V. REYES M.D. An octagenerian woman developed clear cell hidradenocarcinoma, a rare neoplasm of eccrine sweat gland origin, 4 years following pacemaker implantation in her right lateral chest. The tumor immunohistochemically mimicked a metastatic lobular breast carcinoma, for example, strongly positive estrogen, weakly positive progesterone, and weakly reactive mammoglobin. A complete surgical excision of the tumor was complemented with ipsilateral dissection of involved adjacent axillary lymph nodes. Recommended irradiation was refused by the patient. Retrospective 3-year mammogram review, 2-year postsurgery follow-up, and complete postmortem evaluation failed to prove a primary breast malignancy or other metastatic lesion elsewhere. [source] Combined radioguided occult lesion and sentinel node localization for breast cancerANZ JOURNAL OF SURGERY, Issue 7 2004Joon Kim Introduction: The incidence of non-palpable breast lesions requiring intraoperative localization has greatly increased, particularly because of the widespread use of mammographic screening. These lesions have previously been localized preoperatively using hook-wire or carbon track techniques. In the era of increasing acceptance of sentinel node biopsy (SNB) a separate procedure would be required for sentinel node localization (SNL). The present study describes an experience with ultrasound guided radionucleotide occult lesion localization (ROLL) as a reliable alternative that enables SNL synchronously. Methods: Twenty-two patients with proven breast malignancy on core biopsy were enrolled in the present study. Preoperatively, technetium-99m was injected around the lesion under radiological guidance. A ,-probe was then used to locate the lesion and guide its surgical removal. Complete excision was then confirmed immediately by verifying minimal residual radioactivity in the cavity wall tissue. Appropriate SNB then proceeded. Results: The primary breast lesion was identified in all cases except in one, where the radiotracer was injected into the wrong site, giving a miss rate of 1/22 (4.5%). The average size of the tumour was 13 mm (range 6,22 mm) and the closest margins ranged from 0 (1 patient) to 22 mm (mean 7 mm). Two patients had inadequate margins and required further excision giving a re-excision rate of 2/21 (9.5%). SNB specimens included a median of 3.7 nodes/patient Conclusion: Radionucleotide occult lesion localization/SNL is a simple, accurate and reliable method of combining localization of impalpable breast lesions with the localization required for SNB. The miss and re-excision rates compare favourably with the needle-wire systems and carbon tracking techniques. There are significant resource efficiency and time advantages. [source] | ||||||||||
