Expression of nucleoside diphosphate(NDP) kinase, which is homologous to the nm23 gene product in a variety of species, has been found to be inversely associated with metastatic potential. However, the relationship remains controversial according to the tumor cell types and experimental system, with conflicting results from different research groups. In order to determine whether NDP kinase expression serves as a marker for metastatic potential in human skin cancer, we assessed the levels of NDP kinase expression in 9 keratoacanthomas (KAs), 26 squamous cell carcinomas (SCCs), and 25 basal cell carcinomas (BCCs) using immunohistochemistry. The expression of NDP kinase was intense in KA and SCC compared with BCC. However, the difference of NDP kinase expression between KA and SCC was not statistically significant. And there was no statistically significant difference in NDP kinase expression between SCC with metastasis and SCC without metastasis. Our results contradict the hypothesis concerning the possible role of nm23 gene as a metastatic suppressor gene in human skin cancer. The mechanism of overexpression in various tumor cell types and its biological significance in cutaneous carcinogenesis remain to be determined.

We report a case of malignant proliferating trichilemmal tumor showing multiple distant metastases. The patient demonstrated a round mass in the right occipital area for 12 months and the lesion grew rapidly to assume 8x6.5x4cm in diameter, with areas of superficial erosion and crusting within the recent 3 months. The entire lesion was removed with a wide surgical excision. It recurred on the neck area 4 months after excision and the lesion was removed with surgical resection again. There was evidence of multiple metastases on CNS and mediastinal lymph nodes after 6 months. The patient was treated with cisplatin and etoposide combination chemotherapy and a partial response was achieved.

OBJECTIVESBasal cell-like breast cancer is one of the subtypes using molecular typing, and this subtype attracted a wide spread attention. Currently, no uniform diagnostic criteria are available. Most studies demonstrated poor outcomes, but contradictory conclusions appeared recently. The prognosis of basal cell-like breast cancer using different immunohistochemical criteria were analyzed.
METHODSTwo hundred and eighty-four invasive breast cancers with a follow-up information over 5 years were evaluated for ER, PR, HER2, CK5/6, CK14, EGFR expression on tissue microarray immunohistochemically. Based on the results, these cases using four different diagnostic criteria were categorized, namely: Nielsen (ER-/HER2-, CK5/6+ and/or EGFR+), Kim (ER-/PR-/HER2-, CK5/6+ and/or CK14+ and/or EGFR+), Triple-negative (ER-/PR-/HER2-), and basal-CK (CK5/6+ and/or CK14+). 5-year survival information was compared between groups.
RESULTSThe prevalence of basal cell-like breast cancer by Nielsen, Kim, Triple-negative and basal-CK were 15.5% (44/284), 14.8% (42/284), 43.3% (123/284) and 21.1% (60/284) respectively; the recurrence rates were 18.2% (8/44), 21.4% (9/42), 10.6% (13/123) and 11.7% (7/60) respectively. These were higher than recurrence rates for other subtypes, but only the differences by Nielsen's and Kim's criteria were significant. Using Nielsen's and Triple-negative's criteria, basal-like tumors showed shorter 5-year disease-free survival (both P < 0. 01) and overall survival (P < 0.05 and 0.01) than luminal A subtype, using Kim's criteria, basal-like tumors showed a lower 5-year disease-free but not overall survival than luminal A subtype (P < 0.01); no significant difference was found on 5-year survival between basal-like and non-basal-like tumors when typed by basal-CK.
CONCLUSIONBasal cell-like breast cancers are more likely to show more recurrence and worse outcome, but different immunohistochemical diagnostic criteria have an influence on their prognostic analysis, so a uniform diagnostic criteria is essential for the further study of basal-like breast cancers.

OBJECTIVETo study the clinicopathologic features and immunophenotype of centrally necrotizing carcinoma (CNC) of breast; and to study its relationship with basal-like breast cancer.
METHODSThe clinical and pathologic characteristics of 35 cases of CNC were analyzed. Immunohistochemical study for estrogen receptor, progesterone receptor, HER2, CK8/18, 34betaE12, CK5/6, CK14, CK17, smooth muscle actin, p63, vimentin and epidermal growth factor receptor was performed using EnVision method. The surival information of 10 case were obtained.
RESULTSThe age of patients with CNC ranged from 30 to 82 years (mean = 54.2 years). Macroscopically, all tumors were relatively circumscribed, with a mean diameter of 2.4 cm. Histologically, there was a prominent central, necrotic or acellular zone surrounded by a narrow rim of viable tumor cells. The central necrotic foci had the following morphologic patterns: (1) coagulative tumor necrosis associated with various degree of fibrosis or hyaline degeneration (24 cases), (2) predominance of fibrous and scar tissue, with small amount of necrotic debris (8 cases), and (3) infarction (3 cases). The peripheral zone of tumor cells showed features of grade 3 invasive ductal carcinoma in 32 cases and grade 2 in 3 cases. Twenty cases of CNC were associated with ductal carcinoma in-situ. A component of invasive micropapillary carcinoma was identified in 5 cases. Peripheral lymphocytic infiltrates were seen in 17 cases. Immunohistochemical study of 31 cases showed that the expression rate of basal-like markers (83.9%, 26 cases) was higher than that of myoepithelial markers (38.7%, 12 cases). The percentage of basal-like subtype (64.5%, 20 cases) was higher than luminal-A (9.7%, 3 cases), luminal-B (9.7%, 3 cases), HER2 over-expression (12.9%, 4 cases) and null (3.2%, 1 case) subtypes. In 20 cases of basal-like carcinoma, the expression ratio of CK5/6 was highest amongst basal-like markers (18 cases), the other markers ratios of CK17, CK14 and epidermal growth factor receptor were 8/10, 14/19 and 8/16, respectively. Follow-up data were available in 10 patients. The follow-up duration ranged from 15 to 42 months (mean = 21.5 months). The median disease-free and overall survivals were 14.0 and 18.0 months, respectively. Disease progression (as defined by the presence of recurrence, metastasis or tumor-related death) occurred in 9 patients. The mean and median time to disease progression was 16.6 and 13.0 months, respectively.
CONCLUSIONSCNC is a rare subtype of breast carcinoma and has distinctive, easily discernible morphologic features. The majority of CNC exhibits basal-like immunophenotype and carries a poor prognosis. CNC is the typical representative of basal-like breast cancer.
