    Eccrine syringofibroadenoma (Mascaro) Report of two cases.
    J Am Acad Dermatol 1985 Sep 5;13(3):433-436. Epub 2008 Nov 5.
    Department of Dermatology, University of Chicago, IL.
    We report two cases of eccrine syringofibroadenoma. Both patients had a large, solitary hyperkeratotic nodular lesion over the extremities. Histologic sections showed spongelike masses of small cuboidal acrosyringeal cells. Read More

    Basaloid follicular hamartoma: three cases with localized and systematized unilateral lesions.
    J Cutan Pathol 1985 Feb;12(1):55-65
    Two patients having a localized plaque of alopecia on the scalp, and one with a systematized unilateral epithelial nevus exhibited a histologically distinctive form of follicular hamartoma. In the affected areas individual hair follicles were replaced, or were associated with solid strands and branching cords of undifferentiated basaloid cells, filled in between by fibrous stroma resembling either a miniature premalignant fibroepithelial tumor of Pinkus, a small trichoepithelioma, or a basal cell epithelioma. The relation between these 3 patients and cases reported as linear unilateral basal cell nevus with comedones and generalized hair follicle hamartoma associated with myasthenia gravis is discussed.

    [The carcinogenic role of earlier x-ray irradiation of multiple epitheliomas of the back. Critical study of 15 personal cases].
    Ann Dermatol Venereol 1985 ;112(1):13-9
    The authors report 15 cases of multiple epitheliomas of the back, concerning patients who had been previously submitted to X-ray irradiations. Their cases are divided into two groups: the first comprises 11 patients who had undergone lumbar and sacral anti-inflammatory radiotherapy for rheumatologic diseases; the second concerns 4 patients who had had many fluoroscopic examinations for lung tuberculosis and later developed multiple epitheliomas of the back. For each group of patients, they detail the irradiation procedures, and indicate the interval before the subsequent tumoral development, as well as the histologic features. Read More

    [Premalignant fibroepithelial tumors of Pinkus and previous irradiation: report of a survey of 20 patients].
    Ann Dermatol Venereol 1982 ;109(4):355-7
    The search for previous irradiation was done: in nine of the twenty cases radiotherapy or repeated roentgenograms are found, usually twenty years before the start of fibroepithelial tumour. In one case, there was ingestion of arsenic for psoriasis. But in ten cases, no antecedent of irradiation are found (but the interrogatory was sometimes difficult). Read More

    [On five new cases of association of basal cell carcinoma and multiple Pinkus fibroepithelial tumors on the spine following radiation damage to the skin (author's transl)].
    Ann Dermatol Venereol 1979 Nov;106(11):875-82
    The authors report five new cases associating basal cell epithelioma and multiple Pinkus fibro-epithelial tumors on the spine after radiation damage to the skin. One of them had previously published three similar observations: so his experience refers to eight cases. The authors recall similar cases of the literature, they discuss the relations between basal cell epitheliomas and Pinkus premalignant fibro-epithelial tumors of the skin. Read More

    [Fibroepithelial tumors of Pinkus with extra-dorsal, lumbar and sacral localizations -31 cases].
    Ann Dermatol Syphiligr (Paris) 1976 ;103(3):276-9
    In our series of 70 fibroepithelial tumors of Pinkus, 31 tumors were located outside of the dorsal, lumbar and sacral areas. Moreover, we have noted in the literature 32 ectopic localizations. The clinical and evolutive characteristics are the same as for the dorsal, lumbar and sacral tumors. Read More

    [Basal cell epithelioma and multiple fibroepithelial Pinkus' tumors in the lumbosacral region. Discussion of the precipitating role of previous radiotherapy treatment. Apropos of 4 cases].
    Sem Hop 1975 Nov;51(44):2655-64
    The authors report 4 cases of multiple tumors of the lumbo-sacral region with, on histology, a mixture of basal cell carcinomas and fibro-epithelial Pinkus tumours. They were struck by the fact that three of these four patients had received, in this region, radiotherapy numerous years previously. They discuss the role of this radiotherapy in the onset of the disease and the relative importance of this factor and of constitutional factors (Hamartomas). Read More

    Kinetics of cell proliferation in benigh and premalignant tumors of the human epidermis.
    J Natl Cancer Inst 1975 Apr;54(4):825-7
    A double labeling method with two levels of tritiated thymidine was used to study 6 patients with seborrheic keratosis, 1 with a fibroepithelial tumor of Pinkus, and 1 with basal cell nevus syndrome manifesting three pits on the palm of the hand. The two latter types of lesions, known to be able to evolve into basal cell carcinoma, had an increased S-phase duration (18 hr for the germ cells of the palmar pits) as compared with normal epidermis (10 hr). This situation was similar to that observed in basal cell carcinoma, However, the S phase was not lengthened in seborrheic keratosis (9. Read More
