Sebaceous neoplasms of salivary gland origin. Report of 21 cases.

Primary sebaceous tumors of salivary glands are extremely rare, although sebaceous glands are commonly present in parotid and submandibular glands. A review of the files of the Armed Forces Institute of Pathology yielded 21 cases of primary salivary gland sebaceous tumors. Five were sebaceous adenomas, 9 sebaceous lymphadenomas, 5 sebaceous carcinomas and 2 sebaceous lymphadenocarcinomas. Seventeen tumors were located in the parotid gland and one each in the submandibular gland, the minor salivary glands of buccal mucosa and in ectopic salivary gland tissue in a periparotid lymph node. Thirteen tumors occurred in males and six in females. The peak incidence for all the sebaceous tumors, occurred in the sixth and seventh decades. The influence of age, sex, race, clinical symptoms, and pathology on survival is reviewed for each tumor group. Our histopathologic observations strongly suggest that sebaceous lymphadenoma and sebaceous lymphadenocarcinoma arise from sebaceous glandular rests in a lymph node in a fashion similar to that of a Warthin tumor.

[The rabbit ear model as an acnegenicity test. 2. Effect of coal tar on follicle and sebaceous gland epithelium tumor induction].

Tar produced from hard coal was found to be acanthogenic to the interfollicular epiderm of rabbit ear skin and comedogenic to follicular epithelium in short-term (two weeks) and long-term (12 weeks) tests. Histological and autoradiographic experiments revealed a hyperproliferative effect in all cases in long-term tests. This contrasts with the atrophying effects reported by other authors. Tar application reduced the sebaceous gland area per follicle. Benignant epidermal tumours consisting of papillomas with a striking degree of sebaceous gland proliferation appeared on the rabbit ear skin after 8 weeks at the earliest.

The pathology of head and neck tumors: salivary glands, part 3.

The term adenoma is applied to a rather wide variety of histopathologic entities in the salivary glands. These include tumors derived from the ductal epithelium and/or from myoepithelial cells and other salivary-gland elements, such as the sebaceous glands. Within the categories of mixed tumor (pleomorphic adenoma), monomorphic adenoma, clear-cell tumor, and sebaceous lesions, there are also several subtypes, each of which lends further credence to the germinative potential of the salivary tissues. Presented in this report is a clinicopathologic and histogenetic analysis of these lesions. Specifically discussed are mixed tumor, monomorphic adenoma, carcinoma ex-pleomorphic adenoma, clear-cell tumor, sebaceous lymphadenoma, and sebaceous carcinoma.

Vulvar intraepithelial neoplasia and skin appendage involvement.

Vulvar intraepithelial neoplasia may extend into the pilosebaceous units of the hairy and non-hairy skin of the vulva, and inadequate removal may cause treatment failure. We measured with a calibrated microscope the thickness of vulvar intraepithelial neoplasia and the depth to which it extended into the underlying pilosebaceous units of the vulvar skin. The mean thickness of vulvar intraepithelial neoplasia in 329 histologic sections from 62 cases was 0.38 mm; 99.5% of all vulvar intraepithelial neoplasia measured less than 0.77 and 0.69 mm in the hairy and non-hairy skin, respectively. Sebaceous-gland and hair-follicle involvement by vulvar intraepithelial neoplasia was 21 and 32%, respectively. The mean depth of sebaceous-gland involvement was 0.77 mm in the hairy skin and 0.50 mm in its non-hairy counterpart; 99.5% of all vulvar intraepithelial neoplasias extended less than 2.03 and 1.07 mm in the hairy and non-hairy skin, respectively. The mean depth of hair-follicle involvement was 1.04 mm; 99.5% of all hair follicles were involved less than 2.55 mm. Our findings suggest that removal of vulvar intraepithelial neoplasia to a depth of 1.0 and 2.0 mm in the non-hairy and hairy skin, respectively, is appropriate for successful treatment.

Sebaceous gland neoplasia.

Neoplasms with sebaceous differentiation cover a broad spectrum. They range from benign sebaceous hyperplasia and adenomas to locally infiltrative sebaceous epitheliomas which have biologic behaviors similar to basal cell carcinomas, to sebaceous carcinomas which can have very malignant biologic behaviors. In this paper, we have purposely excluded the nevus sebaceus of Jadassohn, a nevoid tumor composed of several cutaneous elements. As sebaceous glands are only one part of this tumor, it is better classified as an organoid nevus.
