Pro-Opiomelanocortin Expression in a Metastatic Breast Carcinoma with Ectopic ACTH Secretion

THE BREAST JOURNAL, Issue 4 2004
Marie-Françoise Pelte MD
Abstract: Cushing's syndrome secondary to ectopic adrenocorticotropic hormone (ACTH) secretion is rarely observed in breast carcinoma and only four cases have been previously published. We report here the case of a 50-year-old woman who presented with a history of diffuse bone pain associated with multiple hepatic, pulmonary, and bone metastases. A core needle biopsy specimen revealed an invasive ductal carcinoma in the right breast. The patient subsequently developed an ACTH-dependent paraneoplastic Cushing's syndrome and she died of arrhythmia and heart failure, despite treatment. At autopsy, immunohistochemical staining showed chromogranin A and ACTH positivity in the breast tumor and a lung metastasis. The mRNA expression of the pro-opiomelanocortin (POMC) gene was detected in tumoral cells by reverse transcriptase polymerase chain reaction (RT-PCR). This is the first case of Cushing's syndrome secondary to ectopic ACTH secretion where the presence of ACTH by immunohistochemistry and the expression of the POMC gene by RT-PCR have both been demonstrated in a breast carcinoma with metastases. The clinical history and the pathologic findings are presented with the methods and results of the molecular analysis. This case illustrates an example of ectopic ACTH syndrome in a breast carcinoma with neuroendocrine (NE) differentiation. This NE phenotype is directly related to the synthesis of ACTH by the tumoral cells. It should be kept in mind that an ectopic ACTH syndrome may be produced not only by small cell carcinoma or endocrine tumors but also by breast cancer. No relationship has been established between NE features and prognostic factors or patient outcome for this peculiar type of breast carcinoma. The demonstration of mRNA POMC in breast carcinoma with NE features suggests a depression and/or an activation of the POMC gene linked to the NE differentiation., [source]


Recovery from Cruciate Paralysis Due to Axial Subluxation from Metastatic Breast Carcinoma: A Case Report

FACS, Walter J. Faillace MD
Abstract: Cruciate paralysis is an uncommon and potentially life-threatening myelopathy thought to arise from injury to the corticospinal tracts at a high cervical spinal level. The authors report on the case of a woman who developed cruciate paralysis secondary to axial subluxation of the cervical spine due to invasion by metastatic breast carcinoma. Correct bedside diagnosis, prompt spinal alignment via halo traction, and surgical spinal decompression with fusion stabilization reversed the paralysis completely. Postoperative antiestrogen medication, spinal radiation, and chemotherapy promoted local tumor control, allowing the patient longevity and good quality pain control. The prompt diagnosis and treatment of cruciate paralysis could effect a good prognosis in a seemingly terminal patient with metastatic spinal breast carcinoma by resolving life-threatening myelopathy, promoting longevity, and assisting with pain control.

Z. Yan M.D.
Abstract Morphologic differentiation of breast carcinoma from nonmammary malignancies in fluid specimens can be a diagnostic challenge. Immunocytochemistry is often employed in the differential diagnosis. In this study, we evaluated the expression of mammoglobin (MGB1) in body-cavity fluid specimens and compared its efficacy as a marker for metastatic breast carcinomas with that of gross cystic disease fluid protein-15 (GCDFP-15). Cell blocks from 40 fluid specimens were immunostained with monoclonal antibodies against MGB1 and GCDFP-15. They included 15 breast carcinomas and 25 nonmammary carcinomas (10 lungs, 10 ovaries, 3 gastrointestinal tracts, 1 kidney, and 1 urinary bladder). Positivity was defined as the presence of cytoplasmic staining in 10% or more carcinoma cells. Thirteen (87%) and seven (47%) breast carcinomas showed positive staining with MGB1 and GCDFP-15, respectively. Three (12%) nonmammary carcinomas (2 ovarian and 1 colonic) showed positive MGB1 staining; one (3%) nonmammary carcinoma demonstrated positive GCDFP-15 staining. The differences of MGB1 and GCDFP-15 staining between breast and nonmammary carcinomas were statistically significant (P < 0.05). Both MGB1 and GCDFP-15 are specific markers for metastatic breast carcinomas in cell block fluid specimens (88 vs. 96%). However, MGB1 is more sensitive than GCDFP-15 as a marker for metastatic breast carcinoma (87 vs. 46%). Diagn. Cytopathol. 2009. © 2009 Wiley-Liss, Inc. [source]


Apocrine carcinoma of the vulva in a band-like arrangement with inflammatory and telangiectatic metastasis via local lymphatic channels

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 1 2003
Takahiro Kiyohara MD
Background Primary adenocarcinomas of the vulva have been classified as sweat gland carcinomas, extramammary Paget's disease, and primary breast carcinomas of the vulva. They share some common histopathologic features. Methods We describe a 72-year-old Japanese woman with apocrine carcinoma of the vulva and local lymphatic metastasis. Results The patient presented with a bruise on her inguinal area. Physical examination revealed a 4 cm × 7 cm, dark-red, irregularly elevated tumor on the left labium majora. Dome-shaped, flesh-colored, small papulovesicles were scattered on the abdomen, accompanied by erythema and induration. The lesion showed a band-like arrangement. General examination revealed multiple bone metastases, particularly in the spine. Microscopic examination revealed a moderately differentiated adenocarcinoma with signet ring cells. A few pagetoid clear cells were present in the hypertrophic epidermis. The peripheral papulovesicles demonstrated the same histopathologic view as in inflammatory and telangiectatic, metastatic breast carcinoma. Tumor cells were positive for various ductal and glandular markers. Estrogen and progesterone receptors were not expressed. Ultrastructural findings suggested differentiation towards apocrine or mammary glands because of the presence of an apocrine process and electron-dense mucous granules. The patient died in spite of combination chemotherapy and irradiation therapy. Conclusions We report a rare case of apocrine carcinoma of the vulva in a band-like arrangement with local lymphatic metastasis which showed the clinical and histopathologic characteristics of inflammatory and telangiectatic carcinoma.

HER2 status in patients with breast carcinoma is not modified selectively by preoperative chemotherapy and is stable during the metastatic process

CANCER, Issue 8 2002
Anne Vincent-Salomon M.D.
Abstract BACKGROUND The objective of this study was to determine whether HER2 expression levels in breast carcinomas were modified by chemotherapy or during the metastatic process. METHODS HER2 expression was analyzed on sequential tissue specimens taken from the primary tumor before patients received preoperative chemotherapy (CT) and from post-CT residual breast tumor or at a metastatic site. The first group of patients included 59 women who presented with T2,T4,N1,N2 breast carcinoma and were treated by preoperative anthracycline-based CT and then underwent surgery. The second group included 44 patients with metastatic breast carcinoma localized to the lung (27 patients) or to the liver (17 patients). HER2 status was determined by immunohistochemistry using an anti-p185HER/neu monoclonal antibody and was classified as overexpressed or not overexpressed. RESULTS Among the patients who received preoperative CT, HER2 overexpression was observed in 15 of 59 patients (25%). A complete pathologic response was observed in 2 of these 15 patients. HER2 still was overexpressed in 11 of 13 remaining residual tumors and was no longer detectable in 2 tumors. In addition, the 29 tumors with no HER2 overexpression before CT remained negative after treatment. In patients with metastatic breast carcinoma, HER2 was overexpressed in 11 of 44 primary tumors (25%). In 9 of these 11 tumors, HER2 overexpression was maintained in the metastases (9 pulmonary metastases and 4 hepatic metastases). In two patients who had low levels of HER2 overexpression in their primary tumors, no staining was observed in the secondary tumor (one pulmonary tumor and one liver tumor). There were no tumors in which the overexpression of HER2 was found only in the metastasis. CONCLUSIONS The current study showed that, in most patients, HER2 overexpression was unchanged after CT and in metastatic sites. No HER2 negative primary tumors became HER2 positive after patients received CT or during the metastatic process. In a few patients, a diminution in the level of HER2 expression was observed after CT or in secondary tumors. This may have been due to a transitory state of altered tumor cells or to the selection of HER2 negative tumor cells clones. Cancer 2002;94:2169,73. © 2002 American Cancer Society.
