Uncommon Condition

Melanomas are primarily tumours of the skin, but rarely occur at other sites like retina and anal canal. Anorectal melanoma is an uncommon condition associated with a very poor prognosis. The patient usually presents with per rectal bleed or mass. These are often misdiagnosed on presentation. Diagnosis is confirmed by biopsy. Treatment is abdominoperineal resection or wide local excision if tumour free margins can be obtained. We present a case of a 60 years old female who presented to the outpatient department with per rectal mass and bleed since 4 to 5 months and was diagnosed with melanoma anal canal on biopsy. CT scan abdomen and pelvis was done. Patient underwent abdominoperineal resection as wide local excision with sphincter saving was not possible due to the location and extent of tumour as seen on CT scan. Patient had an uneventful recovery after the procedure.

AbstractMalignant melanoma limited to the external auditory canal is very rare. These patients present relatively late as compared with melanoma involving other subsites of external ear. However, the tumor is slow-growing but shows aggressive behavior with a poor prognosis when presented late. We have a 44-year-old female who presented with a blackish lesion, which was bleeding on and off from her left ear. She was managed with wide local excision, preserving maximum part of external auditory canal cartilage. The histopathology of the lesion was suggestive of malignant melanoma. After a thorough evaluation, she was kept under close follow-up. Malignant melanoma of external auditory canal shows poor prognosis usually, mainly because of late presentation. Thus, early diagnosis is crucial, as in our case, where wide local excision was sufficing, and the patient is disease-free after 4 years of follow-up.

Extramammary Paget's Disease

The case of a 75-year-old female with invasive extramammary Paget’s disease of the anal margin, without involvement of the anal canal, is reported. The patient underwent wide local excision of the lesion with reconstruction with a double V-Y flap, a biopsy of the inguinal sentinel node, and a laparoscopic temporary colostomy. No guidelines exist on the treatment of this rare disease, and both wide local excision and abdominoperineal resection have been proposed. In the present case, the absence of invasion of the anal canal, also confirmed by intraoperative biopsies on the resection margins, and of local lymph node metastasis, as confirmed by the sentinel lymph node biopsy, allowed a sphincter-sparing operation with good functional and oncological results.

A 60-year-old man presented with malignant melanoma on left heel with left inguinal lymphnode metastasis. He developed right hemiparesis on the 3rd POD of wide local excision of anulcerated lesion of the left sole. CT scan showed multiple cerebral metastasis in the bothparietal lobes. No neurological features also manifested before operation of the primary lesion. Journal of Surgical Sciences (2016) Vol. 20 (1) : 32-33

Long Term Follow Up

Buschke-Löwenstein tumour (BLT) is rare and locally aggressive, and malignant transformation is a possibility. Because there is no consensus on the best treatment approach, the authors present a treatment algorithm based on several case reports. A 57-year-old male patient resorted to surgical consultation with a giant perianal cauliflower-like mass. A BLT was diagnosed. Due to the involvement of the anal sphincter, a wide local excision saving the rectum failed. Abdominoperineal resection was performed. Malignant transformation was diagnosed, and adjuvant radiotherapy was delivered. Clinical evolution was uneventful. Aggressive behaviour despite the absence of malignancy is the hallmark of BLT. The common presentation is an anal mass with a cauliflower-like appearance. Anal verrucous carcinoma and squamous cell carcinoma are the major differential diagnoses. BLT treatment is challenging. Surgery is the first-line treatment, raging from wide local excision to abdominoperineal resection. To improve outcomes, chemoradiation can be used in combination with surgery. Long-term follow-up is mandatory.

We report 2 observations of primary anorectal melanoma, collected over a period of 2 years from December 2017 to December 2019, as well as data from the literature. The patients nevertheless benefited after the histological evidence with an additional immunohistochemical study of an extension assessment made by pelvic MRI and thoracoabdominopelvic CT scan. The patients were classified stage I according to the Slingluff classification. They underwent abdominoperineal resection with definitive left iliac colostomy and adjuvant Chemotherapy.
