1/6. Don't forget your toothbrush!

    patients with rectally inserted foreign bodies can present to accident and emergency departments or general medical practitioners. Rarely dentally related objects are inserted because of their ready availability in the domestic environment. There are many reasons given for their presence in the rectum, most commonly accidental insertion, assault, and psychosexual motives. This case is the first reported incident of a patient using a toothbrush to relieve his pruritus ani and subsequently losing it up into the rectum.

2/6. Squamous cell carcinoma of the anal margin with pruritus ani of long duration.

    BACKGROUND: Anal margin is an unusual location for squamous cell carcinoma (SCC). On rare occasions, anal margin carcinoma is the cause of pruritus ani. OBJECTIVE: To describe a case of SCC of the anal margin with pruritus ani of long duration. RESULTS: A 52-year-old man had been aware of perianal itching for over 10 years. Examination of the perianal area revealed a reddish, eroded, hard nodule that was 2.0 x 1.5 x 0.3 cm in size located in the 3 o'clock position. The histopathologic diagnosis was well-differentiated SCC. The nodule was totally excised with a 1-cm margin. No recurrence or metastases were observed for 7 months. CONCLUSION: When pruritus ani does not respond to conservative therapy and when symptoms have existed for a long time, we should suspect the presence of malignancy.

3/6. Multicentric cloacogenic carcinoma: report of a case with anogenital pruritus at presentation.

    A case of multicentric cloacogenic carcinoma of the perianal skin and vulva in a 79-year-old woman is presented, and the embryologic basis for the multicentricity is discussed. Histologically, cloacogenic carcinoma can be differentiated from other small cell neoplasms that affect the area. Cloacogenic carcinoma should be considered a rare cause of anogenital pruritus. It is important to perform an early biopsy of anogenital lesions that do not respond to conventional therapy.

4/6. pruritus ani: could it be malignant?

    The management of extramammary perianal Paget's disease should include a careful search for an associated carcinoma in the pelvic viscera by means of proctoscopy and x-ray. Such local malignancies as bowen's disease, which may be pigmented and multifocal in this region, and invasive squamous cell carcinoma may first manifest themselves as pruritus ani.

5/6. pruritus ani.

    Although the importance of the anal zone is well known in psychoanalysis, pruritus ani has not been studied recently in the psychoanalytic literature. This paper is presented to show how bisexuality in a male patient has been analysed through pruritus ani as the main presenting symptom. After giving the case history of Fernand, pruritus ani is analysed from three main points of view: phallic, anal and oral. This is done to illustrate the connexions of the psychopathological material at the three stages and their expression through one symptom of the 'instincts and their vicissitudes'. Finally, the importance of the anal stage and its symptomatology as an attempt to diminish the affective charge brought up in the individual by the oral and phallic conflicts is discussed briefly.

6/6. Contact sensitivity to lignocaine.

    Lignocaine is a rare contact allergen, in contrast to other local anaesthetics such as benzocaine, which commonly sensitize. The case of a patient sensitized to lignocaine through the use of a topical medication for the treatment of haemorrhoids is reported. Previous reports show that application of a lignocaine-containing preparation for pruritus ani is the most frequent cause of sensitization to lignocaine. The significance of sensitization to lignocaine is discussed in the light of its widespread use both in local anaesthesia and as an anti-arrhythmic.
