1/344. Mammary Paget's disease with acantholytic features and without any detectable breast tumor.Paget's disease is usually associated with an underlying adenocarcinoma of the breast. The initial manifestation is an eczematous or psoriasiform lesion of the nipple, soon extending to the mammary areola and then to the surrounding skin. The histology of the lesions is characterized by the presence, within the epidermal layer, of the so-called Paget's cells, i.e. large cells with vesicular nucleus and clear cytoplasm. The authors report a recent case of Paget's disease of the breast in a 75-year-old woman, unusual both for clinical course and observed histology. As for the clinico-evolutive aspects, although in the case observed the initial skin lesions appeared 20 years before, the different diagnostic procedures repeatedly performed showed no evidence in this patient of an underlying adenocarcinoma. The histologic aspect, on the other hand, was peculiar since the typical characteristics of an acantholytic disease were evident. The presence of intraepidermal cleavages with lost, at times, of the normal contacts among the cells of the Malpighian layer has been described only once in Paget's disease. This fact caused some diagnostic difficulties: however, the typical finding of the Paget cells, their positivity to histochemical methods such as cytokeratin and acid phosphatase allowed the diagnosis. The authors, at last, evaluate the need of a surgical therapy in Paget's disease of the breast without an underlying adenocarcinoma.- - - - - - - - - - ranking = 1keywords = adenocarcinoma (Clic here for more details about this article) |
2/344. Erosive adenomatosis of the nipple in an eight-year-old girl.Erosive adenomatosis of the nipple (EAN) is a rare, benign neoplasm of breast lactiferous ducts. Peak incidence is in the fifth decade in women. Clinically, it may be mistaken for Paget's disease and, histologically, for adenocarcinoma. Some authors have proposed an association with breast carcinoma and fibrocystic breast changes. Erosive adenomatosis of the nipple is extremely rare in children. Treatment is usually local excision of the nipple. This is the first formal English language case report of EAN in the pediatric age group. It is important for dermatologists to be familiar with this entity to prevent unwarranted breast removal.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |
3/344. The potential oncogenic effect of tamoxifen on the endometrium.We report the case of an in-situ endometrial adenocarcinoma with severe atypical hyperplasia which developed while the patient was on tamoxifen only 1 year after endometrial resection for benign pathology. A 55-year-old woman received tamoxifen as adjuvant therapy for breast cancer treated in 1994. At that time, a benign endometrial polyp was also removed before initiating tamoxifen treatment. In 1997, endometrial resection was performed for benign pathology (atrophic cystic endometrium). In 1998, an endometrial adenocarcinoma was diagnosed. This case illustrates that endometrial resection does not protect women taking tamoxifen against subsequent development of severe atypical lesions.- - - - - - - - - - ranking = 0.66666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
4/344. A leptomeningeal metastasis revealed by sciatica.Meningeal metastatic disease usually occurs as a complication of a brain tumor and is exceptionally isolated in patients with solid tumors. We report the case of a 74-year-old woman admitted for mechanical S1 sciatica refractory to drug therapy. She had been treated for breast cancer three years earlier. Physical findings were pain upon hyperextension of the lumbar spine and absence of the ankle jerks. Analysis of cerebrospinal fluid sampled during an intrathecal glucocorticoid injection showed 1 g/L of protein and 11 normal cells per mm3. Grade 3 L5-S1 spondylolisthesis was seen on plain radiographs, computed tomography scans, and magnetic resonance imaging scans. At that point, the patient developed sphincter dysfunction and motor loss in the left lower limb in the distribution of several nerve roots. Findings were normal from a myelogram and a magnetic resonance imaging study of the brain. A repeat cerebrospinal fluid analysis showed 1.1 g/L of protein and 5 cells/mm3. Because of the discrepancy between the clinical and imaging study findings, the patient was transferred to a neurology department. A third cerebrospinal fluid study showed numerous adenocarcinoma cells, and a repeat magnetic resonance imaging demonstrated a mass in the dural sac opposite L2. A program of monthly intrathecal methotrexate injections was started. A fatal meningeal relapse occurred eight months later. CONCLUSION: This case shows that a leptomeningeal metastasis can cause isolated nerve root pain, and demonstrates the diagnostic value of magnetic resonance imaging and cerebrospinal fluid cytology in patients with atypical symptoms, particularly when there is a history of malignant disease.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |
5/344. methotrexate pneumonitis induced by intrathecal methotrexate therapy: a case report with pharmacokinetic data.A patient with adenocarcinoma of the breast metastatic to the leptomeninges was treated with 10 doses of intrathecal methotrexate (MTX) administered at intervals of 2 days. Following these treatments she developed fever, hypoxemia, and bilateral pulmonary infiltrates without documented pulmonary infection. autopsy findings were consistent with the pneumonitis that has been associated with intermittent oral, intramuscular, and intravenous MTX therapy. It is suggested that this patient's pulmonary process represented MTX pneumonitis following intrathecal MTX. cerebrospinal fluid and serum MTX concentrations determined retrospectively on frozen samples reflect an atypically rapid transport of MTX from this patient's cerebrospinal fluid to a slowly decaying systemic pool. Because of this, serum MTX levels probably exceeded 10-8M during the entire 20-day course of therapy, thus exposing the pulmonary parenchyma to significant drug concentrations for a prolonged interval. It is suggested that these unfavorable pharmacokinetics may have contributed to this patient's susceptibility to MTX pneumonitis.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |
6/344. Multiple primary cancers and HPV infection: are they related?Multiple primary cancers have been reported with increasing frequency in recent years, but the presence of foreign dna sequences of infectious agents in tumours arising in the same patient has so far not been investigated. We report a case of a patient with Hodgkin's lymphoma, an "in situ" cervix carcinoma and an adenocarcinoma of the right and left mammary gland. In all the tumour samples we detected the presence of dna genomic sequences of Papillomavirus type 16. Our results suggest that HPV infection may be an exogenous risk factor even in second primary tumours of non-epithelial origin.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |
7/344. Clinics in diagnostic imaging (35). Metastases to the breasts, skin and bone.A 46-year-old woman presented with multiple skin lumps and right hip pain. Multiple nodules were palpable in the skin over the chest and abdominal wall, and in both breasts. Bilateral mammograms showed multiple solid masses, while ultrasound demonstrated multiple subcutaneous nodules. An osteolytic lesion was seen on the right hip radiograph. Excisional biopsy of a subcutaneous nodule revealed metastatic adenocarcinoma. The diagnosis of metastases to the breast is discussed, together with imaging features of other multiple breast lesions, such as fibroadenomas and cysts.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |

9/344. Paget's disease of the vulva associated with local adenocarcinoma and previous breast adenocarcinoma: report of two cases.We report two women in whom vulval Paget's disease occurred in association with local adenocarcinoma and previous breast adenocarcinoma. The first patient presented at the age of 83 years with moist erythematous changes over the perineum and an indurated area near the anus. biopsy of the indurated area showed Paget's cells throughout the epidermis and, below, adenocarcinoma infiltrating the dermis. Ten years previously, she had undergone a left mastectomy for infiltrating ductal carcinoma of the breast. The second patient was diagnosed as having Paget's disease at the age of 74 years. A vulval biopsy showed Paget's cells in the epidermis but, in addition, there were changes suggestive of adenocarcinoma of the sweat glands. Her symptoms of vulval itching had started at the age of 45 years and had led to a simple vulvectomy at the age of 57 years. Retrospective review of this vulvectomy specimen showed Paget's disease. She had also previously been treated for infiltrating ductal adenocarcinoma of the breast and adenocarcinoma of the rectum. The management of Paget's disease is difficult because of its high recurrence rate and, as illustrated by our two cases, treatment is difficult if the patients are elderly and in poor general health.- - - - - - - - - - ranking = 4.6666666666667keywords = adenocarcinoma (Clic here for more details about this article) |
10/344. calciphylaxis associated with metastatic breast carcinoma.calciphylaxis is a rare disorder associated with calcification of small- and medium-sized blood vessels, and progressive skin necrosis usually seen in the setting of end-stage renal disease (ESRD) and secondary hyperparathyroidism. It has also been observed in primary hyperparathyroidism, hypercalcemia of malignancy (extensive bony metastasis of breast cancer), and an isolated case reported with end-stage liver disease. We report an unusual case of calciphylaxis associated with metastatic breast carcinoma in the absence of renal or parathyroid disease. calciphylaxis has generally been associated with end-stage renal disease and hyperparathyroidism. One previous case report described calciphylaxis occurring in a patient with metastatic adenocarcinoma of the breast and hypercalcemia. Our case represents the second reported case of calciphylaxis associated with osteolytic, metastatic breast cancer. Although ESRD with secondary hyperparathyroidism is the most common presentation of calciphylaxis, this case demonstrates that other conditions that alter normal calcium metabolism must be considered in the differential diagnosis.- - - - - - - - - - ranking = 0.33333333333333keywords = adenocarcinoma (Clic here for more details about this article) |
