Fibrous papules present clinically as benign, asymptomatic, dome-shaped, flesh colored papules on the face. Histologically, fibrous papules are characterized by fibrous stroma with fibroblasts and dilated blood vessels. Multiple variants of fibrous papules have been reported. Although scattered multinucleated cells in fibrous papules have been well described, we report a fibrous papule with abundant multinucleated ganglion-like giant cells that were immunoreactive with CD34. Recognition of such fibrous papule variants is important to avoid misdiagnosis as potentially more worrisome and/or aggressive melanocytic, soft tissue, or neural lesions that may require more aggressive treatment. Indeed, fibrous papules do not commonly appear on the differential diagnosis for lesions with multinucleated giant cells or ganglion-like cells and consideration should be given to their inclusion in the appropriate clinical setting.

The Gorlin-Goltz syndrome is characterized by four primary symptoms: multiple nevoid basal cell epitheliomas that usually undergo malignant transformation; jaw keratocysts that show constant growth; skeletal anomalies; and intracranial calcifications. A myriad of additional findings may also be noted. Among the most frequent are: palmar and plantar pits, a characteristic flattened facies and broad nasal root, frontal and parietal bossing, mandibular prognathia, hypertelorism, strabismus, dystrophia of the canthi, and clefts of the lip, alveolus, and/or palate. In this study, we review the literature and our 25 cases of Gorlin-Goltz syndrome patients, questioning their incidence of cleft formations (8.5%) as compared to the general population (0.1%). It is our contention that all patients who present with an orofacial cleft warrant deeper investigation as to the presence of additional signs indicative of Gorlin-Goltz syndrome. The nevi turn malignant with time, and thus, early diagnosis, follow-up, and treatment are imperative.

The carcinogenicity and chronic toxicity of hydrazine monohydrate was examined by administrating hydrazine monohydrate in drinking water to groups of 50 F344/DuCrj rats and 50 Crj:BDF1 mice of both sexes for two years. The drinking water concentration of hydrazine monohydrate was 0, 20, 40 or 80 ppm (wt/wt) for male and female rats and male mice; and 0, 40, 80 or 160 ppm for female mice. Survival rates of each group of males and females rats and mice were similar to the respective controls, except female rats administered 80 ppm. Two-year administration of hydrazine monohydrate produced an increase in the incidences of hepatocellular adenomas and carcinomas in rats of both sexes along with hepatic foci. In mice, the incidences of hepatocellular adenomas and carcinomas were increased in females, and significantly increased incidences of hepatocellular adenomas in females administered 160 ppm were observed. Thus, hydrazine monohydrate is carcinogenic in two species, rats and mice. Additionally, non-neoplastic renal lesions in rats and mice and non-neoplastic nasal lesions in mice were observed.

The occurrence of neoplasms in injury scars--as consequence of occupational accidents--may lead to compensation according to the statutory accident insurance regulations. According to newer regulatory attempts in occupational dermatology, certain criteria have to be met before the diagnosis of a neoplasm induced by a scar is accepted and compensation is due.. Based on a retrospective analysis of 217 dermatological claim files between 2007 and 2009 of the IPA (including 22 follow-ups), medical opinions on neoplasms developing in possible occupational scars were re-evaluated using criteria of the German social accident insurance and the Bamberg medical bulletin, part II (Bamberger Merkblatt, BM II) to see how well they qualified for recognition as an occupational or accident-related disorder.. Three cases were identified where a neoplasm was suspected of having developed in an occupationally-related scar. One of the insured events entitled for compensation. Following the guidelines of the BM II, this case was approved as an occupational disease secondary to injuries with resultant reduction in earning capacity, whereas the others did not meet the requirements.. Two problems in evaluating malignant tumors in occupational scars are the long latency period and the documentation of a scar. The tumor excision specimen should be histologically re-examined to document the presence of an associated scar.

Rhinophyma, the end stage in the development of acne rosacea, is characterized by sebaceous hyperplasia, fibrosis, follicular plugging, and telangiectasia. Although it is commonly considered a cosmetic problem, it can result in gross distortion of soft tissue and airway obstruction. Basal cell carcinoma (BCC) is a rare finding in patients with rhinophyma. The objective of this study is to review the literature of BCC in rhinophyma and report on a case. A 70-year-old male presented with long-standing rosacea that resulted in a gross nasal deformity. The patient suffered from chronic drainage and recurrent infections that failed conservative treatment with oral and topical antibiotics. The patient decided to proceed with surgical intervention and underwent tangential excision and dermabrasion in the operating room. Since 1955 there have been 11 cases reported in the literature. In our case, the pathology report noted that the specimen had an incidental finding of a completely resected BCC. The patient did well postoperatively and at follow-up remains tumor-free. Despite the uncommon occurrence of BCC in resection specimens for rhinophyma, we recommend that all specimens be reviewed by a pathologist. If BCC is detected, re-excision may be necessary and careful follow-up is mandatory. Larger studies would be needed to determine the correlation between the 2 conditions.

Some authors have used sebaceous epithelioma as a synonym for basal cell carcinoma (BCC) with sebaceous differentiation. However, our review of the literature revealed that definite cases of BCC with sebaceous differentiation that provide adequate clinical and histopathologic information are scarce. We present the case of a 72-year-old woman with a pigmented nodular lesion on her right ala nasi region, clinically diagnosed as pigmented BCC. Histopathologically, this nodular lesion, which was completely excised, showed typical features of BCC. It was noteworthy that within one aggregation of the presented BCC, tiny and small duct-like structures lined by cornified layers with a crenulated inner surface were seen. Vacuolated cells were scattered within a few aggregations, and they had foamy, bubbly cytoplasm and starry nuclei. The vacuolated cells were immunohistochemically positive for epithelial membrane antigen (EMA). These histopathologic findings demonstrated unquestionable sebaceous differentiation in this BCC, namely BCC with sebaceous differentiation, which should be distinguishable from both sebaceoma and sebaceous carcinoma. The small duct-like structures lined by eosinophilic cuticle, indicating apocrine differentiation, were also observed in this BCC.

A 54-year-old male had a dome-shaped and skin-colored nodule on his nose. Histopathologically, we diagnosed this neoplasm as a low-grade sebaceous carcinoma rather than a sebaceoma based on the scanning magnification and cytology. This low-grade sebaceous carcinoma was associated with glandular structures. We regarded the glandular structures as those of apocrine glandular differentiation based on 1) the histopathologic features of the glandular structures formed by columnar luminal cells with evidence of decapitation secretion; 2) the expression of cytokeratin (CK) 19, CK8, CK8/18, and CK7 in the luminal cells; 3) the positive reaction of carcinoembryonic antigen and epithelial membrane antigen on the luminal surface and in the cytoplasm of the luminal cells; and 4) the common embryologic origin of the folliculosebaceous-apocrine unit. We found CK15 expression in undifferentiated cells within the mantles of normal hair follicles, suggesting that sebaceous stem cells might exist in mantles as follicular stem cells exist in bulge areas. Pluripotent stem cells in the folliculosebaceous-apocrine unit can give rise to follicular stem cells, sebaceous stem cells, and apocrine stem cells. Our patient's neoplasm showed apocrine glandular differentiation and partial immunohistochemical positivity for CK15 in the neoplastic aggregations. We believe this neoplasm originated from pluripotent stem cells destined to become sebaceous stem cells or from sebaceous stem cells, which also have the ability to differentiate within apocrine glands.

The present study comprises 43 patients with sinonasal papillomas operated on between 1990 and 1997 at the ENT Department, University Hospital of Zurich. Histology showed 5 cases of exophytic papilloma (EP) (12%), 34 cases of inverted papilloma (IP) (79%) including 4 cases of associated carcinoma (9%), and 4 cases of columnar cell papilloma (CCP) (9%). Recurrence developed in 6 of 41 patients (2 EP, 4 IP) (15%). HPV was detected in 4 of 37 specimens (11%) both by in situ hybridization (ISH) and polymerase chain reaction (PCR). HPV-11 was found in 3 lesions (2 EP, 1 IP), whereas HPV-6b was detected only in one lesion (1 EP). Altogether 3 of 5 EP (60%), one of 29 IP (3%) and one of 6 recurrent papillomas (1 EP) (17%) tested positive for HPV. Our findings suggest a possible role for HPV in the pathogenesis of exophytic papilloma. As no correlation was found with associated malignancy and recurrence of disease, screening for HPV seems not to be useful as a prognostic parameter.

Thirty cases of inverting papilloma were reviewed retrospectively. The histology was reviewed and correlated with the clinical findings. The histology, site and clinical course allow these papillomas to be divided into three types: solitary nodular inverting papilloma, multilocalized nodular inverting papilloma, and myxoid inverting papilloma. Every group has its own prognosis. This separation makes it possible to decide the therapy, particularly the extent of the operation.
