11/109. Intracystic papillary carcinoma in the male breast. A case report.

    Male breast cancer is a rare disease with an incidence between 0.5% and 2.4% of that in women. We report a case of intracystic papillary carcinoma of the breast in a 75-year-old Japanese man. The macroscopic features of the carcinoma could be accurately demonstrated by pneumocystography and ultrasonography preoperatively.

12/109. A case report of advanced male breast cancer with an objective response to tamoxifen treatment.

    A 70-year-old man presented with a firm tumor in his right breast first noticed eight years ago.The tumor had enlarged gradually and had produced an ulcer with bleeding. On physical examination, a huge tumor entirely occupied the right breast and extensively had infiltrated the chest wall.Chest X-ray and CT showed massive pleural effusion and multiple small nodular lesions in the lung. Invasive ductal carcinoma of the breast was diagnosed by incisional biopsy,confirming advanced breast cancer with lung metastases and bilateral pleural effusion(T4cN2M1, Stage IV). Because ER and PgR levels were 110 fmol/mg and 190 fmol/mg, respectively, and because his general condition was poor, we selected medical treatment with tamoxifen(TAM). Thirty-two weeks later, the tumor had showed pronounced reduction with scarring. The patient underwent local excision of the scar tissue. The quality of life of the patient was favorably improved and no severe adverse events were observed. The tumor in the chest wall recurred two months after the end of TAM treatment, possibly because the patient did not accept continuous TAM therapy. The patient died from complications of brain metastasis 32 months after the start of TAM treatment. We report a rare case of advanced male breast cancer and on the effectiveness of continuous TAM treatment.

13/109. Karyotypic findings in two cases of male breast cancer.

    Male breast cancer is uncommon; so far, only 10 cases with chromosome banding analysis have been published. We report the cytogenetic findings of two invasive breast cancers in two Caucasian men lacking a history of familial breast cancer and more than 70 years of age. Both had ductal carcinomas with lymphangiosis carcinomatosa and positive lymph nodes at diagnosis. Strong expression of estrogen receptor, weak expression of progesterone receptor, and lack of expression of androgen receptor by both tumors were demonstrated by immunohistochemistry, as well as lack of expression of p53 and C-ERB-B-2. The karyotypes were 45 approximately 46,XY,-Y[4],-7[2], 8[2],t(8;12)(q21;q24)[3], del(9)(q22)[3],del(11)(p11p14)[5],del(18)(q21)[7], t(19;20)(p10;q10)[8] [cp13] and 61 approximately 69,XXXY,-Y[3], del(2)(p21)[4],del(3)(p22q26)[3],-4,-4[5], 5, 5[5], dic(5;11)(p14;q23)[3],del(6)(q23)[4],del(8)(p21)[3],-9[4],-11[4], i(12)(p10)[4],-16[3],del(17)([13)[5],del(18)(q21)[4], 19[5], 20[4][cp7], respectively. Although the available data on male breast cancer are still very limited, our findings confirm that gain of an x chromosome, loss of the y chromosome, gain of chromosome 5, and loss of material from chromosomes 17 and 18 are nonrandom aberrations in male breast cancer. trisomy 8, characteristic of ductal carcinomas, was found in one case.

14/109. A case of breast cancer associated with juvenile papillomatosis of the male breast.

    Juvenile papillomatosis of the breast (JPB) was first described in 1980 and is occasionally associated with breast cancer. The literature reports only four cases of JPB in males; none of them associated simultaneously with breast cancer. We present a case of a male with JPB associated with a ductal carcinoma in the same gland.

15/109. tumor lysis syndrome following hemi-body irradiation for metastatic breast cancer.

    tumor lysis syndrome (TLS) is a rare serious acute complication of cancer therapy, reported mainly following chemotherapy in patients with large tumor load and chemosensitive disease. These are mainly patients with non-Hodgkin's lymphoma, leukemia and rarely in solid tumors. It is less frequently described after radiotherapy for lymphoid and hematological malignancies. TLS following radiotherapy for solid tumors is a very rare complication. In this report/review we describe a seventy-three-year-old male patient with progressive metastatic carcinoma of the breast to the lungs, liver and bone. He was referred for radiotherapy because of generalized bony pains. The patient was planned for sequential hemi-body irradiation starting with the more symptomatic upper half body. After premedication, he was given 8.5 Gy to the mid point at the maximum chest separation with anterior lung attenuator limiting uncorrected lung dose to 6.15 Gy. A further 3.5 Gy electron boost to the fungating breast tumor was given to the 100%. Forty-eight hours after irradiation he developed hyperkalemia, hyperphosphatemia, hyperuricemia, hypocalcemia and renal failure. These clinical and biochemical changes are typical of tumor lysis syndrome (TLS). Despite hydration, and treating the hyperuricemia, the patient developed coma and died eight days after irradiation. The prophylaxis and management of TLS and in high-risk patients are described to avoid this frequently fatal complication.

16/109. Tc-99m tetrofosmin uptake in male breast cancer.

    breast carcinoma occurs rarely in men. Its imaging by mammography is difficult because male breast tissue is normally small in volume and adequate compression is not possible, which is a prerequisite for performing mammography. The authors describe a 65-year-old man with a right breast mass in whom the result of fine-needle aspiration cytology was inconclusive. A mammogram was also noncontributory because adequate compression was not possible as the mass was tender. Tc-99m tetrofosmin scintimammography showed intense focal uptake in the right breast. Excision biopsy confirmed the diagnosis of breast carcinoma.

17/109. rectus abdominis myocutaneous flap in reconstruction for advanced male breast cancer: case report.

    A case of advanced male breast cancer which masqueraded as recurrent abscess of the right breast is presented to highlight the role of contra-lateral rectus abdominis pedicled myocutaneous flap in providing adequate skin and soft tissue cover in male breast reconstruction. This was carried out for this patient following a modified radical mastectomy for stage III (T2b, N2, M0) intraductal carcinoma of the breast. The patient has remained well without clinical features of distant metastasis at a follow up period of two years despite periodic excision of locally recurrent cancer nodules from the affected breast.

18/109. Male breast cancer in Cowden syndrome patients with germline PTEN mutations.

    Cowden syndrome (CS) (OMIM 158350) is a multiple hamartoma syndrome associated with germline mutations in the PTEN tumour suppressor gene. While CS is characterised most commonly by non-cancerous lesions (mucocutaneous trichilemmomas, acral and palmoplantar keratoses, and papillomatous papules), it is also associated with an increased susceptibility to breast cancer (in females) and thyroid cancer, as well as non-cancerous conditions of the breast and thyroid. Here we report two cases of male breast cancer occurring in patients with classical CS phenotypes and germline PTEN mutations. The first subject was diagnosed with CS indicated primarily by mucocutaneous papillomatosis, facial trichilemmomas, and macrocephaly with frontal bossing at the age of 31 years. He developed breast cancer at 41 years and subsequently died of the disease. A PTEN mutation, c.802delG, was identified in this subject, yet none of his family members showed evidence of a CS phenotype, suggesting that this PTEN mutation may be a de novo occurrence. The second subject had a CS phenotype including multiple trichilemmomas and thyroid adenoma, developed male breast cancer at 43 years, and died of the disease at 57 years. He was a carrier of a PTEN mutation c.347-351delACAAT that cosegregated with the CS phenotype in affected family members. These two cases of male breast cancer associated with germline PTEN mutations and the CS phenotype suggest that CS may be associated with an increased risk of early onset male as well as female breast cancer.

19/109. tamoxifen-failed male breast cancer with a high level of circulating estrogen: report of a case.

    We report herein the case of a 40-year-old man with grade II invasive ductal carcinoma of the breast (pT1, pN0, M0: stage I) in whom a recurrence developed shortly after completion of a 2-year course of tamoxifen and 5-fluorouracil therapy following a mastectomy. Although the metastatic tumor was estrogen receptor-positive, hormone therapy combined with chemotherapy had no significant effect on tumor growth, and the patient died from disseminated tumors 2 years 6 months after completion of the adjuvant therapy. It is noteworthy that the circulating estradiol level increased from 18.0 to 892.3 pg/ml during the period of tumor progression and dissemination. We interpret these findings as an indication of high aromatase activity in the metastatic tumors. We suggest that extending tamoxifen treatment to 5 years or longer be recommended for the standard adjuvant hormone therapy of male breast cancer to prevent the early recurrence of hormone-responsive disease.
