with distinct cell borders and a gro u n d - glass cytoplasm. A prominent eosinophilic infiltration in the stroma helps to separate the tumour from non-keratinizing squamous cell carcinoma {1701}. Prognosis and predictive factors The prognosis of adenosquamous carcinoma remains uncertain {68}. A Fig. 5.32 Adenoid basal carcinoma. A Clusters of basaloid cells show mature central squamous differentiation. B Note small clusters of basaloid cells adjacent to cystic glands. B Adenoid cystic carcinoma Definition A carcinoma of the cervix that resembles adenoid cystic carcinoma of salivary gland origin. Epidemiology Most of the patients are over 60 years of age, and there is a high proportion of Black women {849}. Clinical features The majority of patients present with postmenopausal bleeding and have a mass on pelvic examination {849}. Fig. 5.33 Atypical carcinoid. Islands of tumour cells with moderate nuclear atypia are surrounded by fibrous stroma. Fig. 5.34 Small cell carcinoma. Note the loosely packed neoplastic cells with scant cytoplasm. Histopathology This rare tumour of the cervix has a histological appearance similar to its counterpart in salivary glands. The characteristic cystic spaces are filled with a slightly eosinophilic hyaline material or basophilic mucin and are surrounded by palisaded epithelial cells {849}. In contrast to adenoid cystic carcinoma of salivary gland, the cervical carcinomas show greater nuclear pleomorphism, a high mitotic rate and necrosis {849}. A solid variant has been described {65}. Immunostains for basement membrane components such as collagen type IV and laminin are strongly positive {1918}. In contrast to an earlier study {849}, the majority of the tumours stained for S-100 protein and HHF35 suggesting myoepithelial differentiation {1059}. The differential diagnosis includes small cell carcinoma, adenoid basal carcinoma and non-keratinizing squamous cell carcinoma. Histogenesis This tumour, basaloid squamous cell carcinoma and adenoid basal carcinoma are part of a morphological and biological spectrum of basaloid cervical neoplasms, and a putative reserve cell origin has been suggested {1059}. Circumstantial evidence suggests that adenoid 278 Tumours of the uterine cervix
A Fig. 5.35 Large cell neuroendocrine carcinoma. A The tumour is composed of large cells with pleomorphic nuclei and frequent mitotic figures. B Note the strong cytoplasmic immunoreactivity for chromogranin A. B basal carcinoma may be a precursor of adenoid cystic carcinoma {1059}. Prognosis and predictive factors The tumours frequently recur locally or metastasize to distant organs and have an unfavourable prognosis. Adenoid basal carcinoma Definition A cervical carcinoma in which rounded, generally well diff e rentiated nests of basaloid cells show focal gland formation or sometimes central squamous differentiation. Epidemiology Adenoid basal carcinoma is a rare tumour. The patients are usually more than 50 years old. Clinical findings Patients are usually asymptomatic and without a clinically detectable abnormality of the cervix. The tumour is often discovered as an incidental finding. Histopathology The histological appearance shows small nests of basaloid cells, almost always beneath and often arising from CIN or small invasive squamous cell carc i n o m a s {849}. The cells are small with scanty cytoplasm and are arranged in cords and nests with focal glandular or squamous diff e re n- tiation. There is frequently associated CIN {332,849}. The differential diagnosis includes other small cell tumours {2280}. Histogenesis This tumour, basaloid squamous cell carcinoma and adenoid cystic carcinoma are part of a morphological and biological spectrum of basaloid cervical neoplasms and a putative reserve cell origin has been suggested {1059}. Prognosis and predictive factors The tumour is low grade and rare l y metastasizes. Neuroendocrine tumours The group of neuroendocrine tumours includes carcinoid, atypical carc i n o i d , large cell neuroendocrine carcinoma and small cell carcinoma {63,2803}. Neuroendocrine differentiation is demonstrated with pan-neuroendocrine markers such as chromogranin A, synaptophysin and neuron specific enolase. A variety of peptides and hormones are also present, such as calcitonin, gastrin, serotonin, substance P, vasoactive intestinal peptide, pancreatic polypeptide, somatostatin and adre n o c o rt i c o t ro p h i c hormone {22}, but their clinical significance is limited {2612}. Carcinoid Generally benign, carcinoids have the same characteristic organoid appearance as observed in other sites. The d e g ree of nuclear atypia and mitotic activity are important in the differential diagnosis between typical and atypical carcinoids. Atypical carcinoid An atypical carcinoid is a carcinoid with cytologic atypia that exhibits increased mitotic activity (5-10 per high power field) and contains foci of necrosis {63}. Small cell carcinoma Small cell carcinomas account for 1-6% of cervical carcinomas {22}. Squamous or glandular diff e rentiation may be present {22,248, 830,1761,2219}. The 5-year survival rate is re p o rted to be 14-39% {22,248,2803}. Large cell neuroendocrine carcinoma Large cell neuroendocrine carcinoma is a r a re tumour that often has focal adenocarcinomatous diff e rentiation {592a, 1521a, 2361a}. The tumour cells have abundant cytoplasm, large nuclei and pro m i n e n t nucleoli. Mitoses are frequent. The diff e re n- tial diagnosis includes non-neuro e n d o c r i n e u n d i ff e rentiated carcinoma, adenocarc i n o- ma with neuroendocrine features, metastatic neuroendocrine carcinoma and undiff e r- entiated sarcoma. The tumours are aggre s- sive and appear to have a similar outcome to small cell carcinoma {1006}. Undifferentiated carcinoma U n d i ff e rentiated carcinoma is a carc i n o- ma lacking specific diff e rentiation. The diff e rential diagnosis includes poorly diff e r- entiated squamous cell carcinoma, aden o c a rcinoma, glassy cell carcinoma and large cell neuroendocrine carc i n o m a .
