[Adenocarcinoma of the ampulla of Vater revealed by prurigo].

Chronic prurigo may reveal several internal diseases. Its association with a solid neoplasia is rare. We report an exceptional case of chronic prurigo revealing surgically curable adenocarcinoma of the ampulla of Vater.

[Chronic ulceration of the hand in a mechanic: epidermoid carcinoma should be suspected].

Cutaneous squamous cell carcinoma is a malignant tumor developed from the epidermis or the squamous mucosa. It may occur de novo or, most often, on precancerous lesions, including actinic keratoses. This tumor can sometimes be secondary to physical or chemical hazardous conditions encountered during the professional activity.

[Perineal verrucous lesions].

Verrucous lichen planus (VLP), is a chronic inflammatory dermatosis mainly involving the lower limbs. It rarely affects the perineal area, where it occurs in association with other mucocutaneous lichen lesions. We here report the case of a 51-year old patient with isolated perineal verrucous lichen planus.

[Shoulder tumor of startling appearance].

Chondrosarcoma is a malignant tumor of bone of mesenchymal origin which usually occurs in people after age 40 at the level of the pelvis and the shoulder. We report the case of a 65-year old female patient, with no particular past medical history, with impaired general condition, hospitalized for exploration of a large tumor of the right shoulder, evolving over 3 years. Clinical examination showed giant, humpbacked, hard, adherent tumor measuring 44 × 32 cm along its longer axis, with inflammatory signs associated with signs of vasculo-nervous compression.

[Exophytic tumor of the scalp].

Proliferating trichilemmal tumor (PTT), still referred to as proliferative trichilemmal cyst (TC), is an uncommon malignant adnexal tumor originating from the cells of the outer root sheath of the hair follicle or, more often, from a trichilemmal cyst, following multiple trauma and/or recurrent inflammation. We report the case of a 64-year old female patient, with no particular previous history, presenting with tumor of the scalp gradually evolving over 18 months. Clinical examination showed a painless, firm, adhering ulcero-budding tumor mass measuring 12 cm along its longer axis at the level of the vertex.
