1/80. Recurrent squamous-cell carcinoma arising in sacrococcygeal pilonidal sinus tract: report of a case and review of the literature. PURPOSE: carcinoma arising in a pilonidal sinus is a rare complication. This study reports the case of a patient with recurrent squamous-cell carcinoma arising in a sacrococcygeal pilonidal sinus tract. methods: This patient was treated with a wide local excision and mesh grafts. Three months later the patient was treated with adjuvant radiation therapy. RESULTS: The patient died two years later from recurrence in inguinal lymph nodes, liver, and lungs. CONCLUSION: Some authors propose consideration of treatment with adjuvant chemotherapy and radiation therapy in addition to complete local excision as a possible means to decrease the local recurrence rate.

2/80. pilonidal sinus of the penis. A report of two cases, one of them associated with actinomycosis. pilonidal sinus is a long-standing chronic inflammatory condition which occurs most commonly in the sacrococcygeal area and it is rare in the penis. Two cases of penile pilonidal sinus in patients aged 25 and 28 years are reported and the literature is reviewed. The lesion is acquired and has to be distinguished from balanoposthitis, epidermal cyst and carcinoma. For pilonidal sinus to occur at this site, it is hypothesized that the coronal sulcus acts as a cleft where hair may accumulate and be driven into the shaft and prepuce by the natural movement between these two surfaces. One of our cases was associated with actinomycosis. actinomycosis associated with pilonidal sinus of the penis is extremely rare and there are only two previous reports. It is suggested that pilonidal sinus may have been predisposed to the infection with the actinomyces organisms. Information stating that penile pilonidal sinus and actinomycosis may occur simultaneously is necessary to accomplish an early diagnosis. ( info) |
3/80. Fine-needle aspiration cytology of metastatic squamous-cell carcinoma arising in a pilonidal sinus, with literature review. Fewer than 50 cases of carcinoma arising in a pilonidal sinus have been reported, with only 5 patients having documented inguinal lymph node metastases. This is the first report of the fine-needle aspiration (FNA) diagnosis of this uncommon clinical situation of squamous-cell carcinoma arising in a pilonidal sinus, metastatic to an inguinal lymph node. We report on a 59-yr-old male with squamous-cell carcinoma arising in a pilonidal sinus who presented with inguinal adenopathy. FNA biopsy of a lymph node was performed, resulting in a diagnosis of metastatic squamous-cell carcinoma. FNA biopsy is useful in the evaluation of patients with inguinal adenopathy and a history of malignancy arising in a pilonidal sinus. The possibility of this rare complication should also be considered when metastatic squamous-cell carcinoma to an inguinal lymph node is diagnosed by FNA cytology in patients having an unknown primary except for a change in a long-standing pilonidal cyst.

4/80. Mature presacral teratoma in an adult male: a case report. Presacral teratomas are rare tumors derived from more than one embryonic germ layer and are usually diagnosed in infancy. It has been estimated that the incidence of presacral teratoma in children ranges from 1 in 30,000 to 1 in 43,000 live births. However, the diagnosis of these tumors in adults is extremely rare. H. head et al. reviewed the world literature in 1975 and found only 71 reported cases. Since that time, an additional 14 cases have been reported, and only one of these was found in the united states. This study reports a case of an adult male who presented with recurrent infected pilonidal cysts that proved to be benign presacral teratoma at biopsy. The patient underwent resection by left hemisacrectomy and primary closure using a posterior approach and, since this procedure, has had no evidence of recurrence. The case is presented along with a review of the relevant literature. ( info) |
5/80. Pilonidal cyst on the vault. Case report. Pilonidal cysts and sinuses are described as dermoid cysts which contain follicles of hairs and sebaceous glands. They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneous tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration. ( info) |
| We describe a case of steatocystoma multiplex with an unusual clinical manifestation. A 5-year-old girl had 8 papulonodular lesions arranged in a linear fashion on the left side of the nose. These had been present at birth. Histologically the lesions showed the typical features of steatocystoma multiplex. There was no family history of similar lesions. This is the second case of linear steatocystoma multiplex, a rare variant of steatocystoma multiplex. ( info) |
7/80. Closure of hemicorporectomy with bilateral subtotal thigh flaps. Hemicorporectomy is typically performed with a circumferential truncal incision, and the wound is closed primarily. Wound disruption is a common complication, especially at the base of the wound closure and posteriorly at the lumbar vertebral level. We report a case of the use of bilateral subtotal thigh flaps for the closure of a hemicorporectomy wound in a patient with a defect extending up to the high lumbar region. The subtotal thigh flap is a well-vascularized thick flap that provides a firm support for the abdominal viscera and is a large flap that can be used to close even a high lumbar defect. ( info) |
8/80. Lumbar osteomyelitis and epidural abscess complicating recurrent pilonidal cyst: report of a case. PURPOSE: This study was conducted to report the rare presentation of lumbar osteomyelitis and epidural abscess as a complication of a pilonidal cyst. methods: A case report is presented. RESULTS: We describe the rare case of a male patient with diabetes with a recurring pilonidal cyst who developed a lumbar osteomyelitis and epidural abscess three weeks after pilonidal cyst excision with epidural anesthesia, with a fatal outcome despite emergency treatment. CONCLUSIONS: life-threatening complications should be kept in mind in high-risk patients with repetitive surgery and neurologic involvement. ( info) |
9/80. A case of sacro-coccygeal chordoma masquerading as pilonidal sinus. chordoma is a rare, slow-growing, but locally aggressive malignant tumour derived from the primitive notochord. pilonidal sinus disease, characterised by communicating granulating natal cleft tracts and abscesses, is a common condition. We report a case of a sacro-coccygeal chordoma diagnosed incidentally on surgical exploration of a case of presumed pilonidal disease. ( info) |
| We report three cases of interdigital pilonidal sinus including a case of a woman with this condition. Previous reports that surgical excision is curative in all cases are not supported by our experience. ( info) |
