A female patient with Gardner's syndrome was treated with delta1-testololactone (200 mg daily) because of growth of a large desmoid tumor in the pelvis and lower abdomen and a tumor in a scar from a previous laparotomy. There was also pain and swelling of the left leg. An immediate effect of the drug therapy was complete relief of pain followed shortly thereafter by disappearance of the edema of the leg. After two months, the numerous sebaceous cysts were less prominent. The gross measurements of the diameter of the pelvic and lower abdominal tumor clearly demonstrated tumor shrinkage following therapy. Small polyps scattered over the rectal mucosa and numerous osteomata were not demonstrably affected. After one year of treatment with delta1-testololactone, a laparotomy for partial small bowel obstruction was necessary. Obstruction was caused by the involvement of small bowel mesentery and the bowel itself in a contracted residuum of dense fibrous tissue. Substitution of theophylline and chlorothiazide for the testololactone in Januray 1974 was followed by further diminution of the measurable abdominal and pelvic desmoids. All of these compounds synergize the action of 3',5'-adenosine monophosphate and at least the latter two may function by inhibiting the action of 3',5'-adenosine monophosphate diesterase.

This case illustrates the importance of intraoperative monitoring of neuronal function to help separate tumor tissue from neural tissue in a 54-year-old patient with left shoulder pain resulting from a desmoid tumor. Preoperative nerve conduction and electromyographic studies showed a lesion in the lateral cord of the brachial plexus, which was found to be intimately involved with the tumor mass and was splayed into a very thin effaced sheet of neural tissue. Stimulation of the tumor/nerve tissue mass proximal to the lesion was impossible due to the invasion of the brachial plexus by the tumor. The technique that was adapted for this unusual presentation was to stimulate the tumor/nerve tissue mass itself and record compound muscle action potentials distally. With the technique described, a subtotal resection of an aggressive fibromatosis enmeshed in the proximal brachial plexus was possible, and excellent relief of pain symptoms and retention of functional capabilities of the involved extremity were achieved.

Elastofibroma dorsi was diagnosed in seven patients at the Columbia-Presbyterian Medical Center between 1976 and 1986. The ages of the patients ranged from 6 to 79 years (mean 49.3 years). No sex predominance was seen. Five cases of unilateral subscapular tumor and two cases of bilateral masses were identified. Four patients had pain with arm motion, and the remaining patients were free of symptoms. A nonencapsulated soft tissue mass elevating the scapula was identified by computed tomography. Incisional biopsy was performed in all cases, followed by local excision of the tumor. On gross examination, these lesions were firm and rubbery. Histologic evaluation demonstrated a slightly hypercellular fibrous tissue that contained variable numbers of fragmented elastic fibers. All patients with symptomatic tumors had complete relief of their pain after the operation. No recurrences were observed. Clinically, elastofibroma may mimic sarcoma and fibromatosis (extraabdominal desmoid tumors). Whether elastofibroma is a true neoplasm or a reactive fibrous lesion that produces not only collagen, but also abnormal elastic fibers, has been the subject of controversy and remains undetermined.

Although musculoaponeurotic fibromatosis (MAF) is a well-recognized entity, it still provides a histologic diagnostic enigma, particularly in its distinction from a well-differentiated fibrosarcoma. The lesion is histologically identical to a desmoid tumor. The lesion appears as a firm swelling in a limb or limb girdle, with a rare incidence of pain. Although it is more common in the second to fourth decades (premenopausal women predominantly), it does occur in children. The sex incidence in children is equal. A multicentric pattern of behavior may be evident. The mainstay of treatment has been surgical excision of varying extent. Local excision, even if radical, may be followed by up to a 65% recurrence rate. In this review, 40% of the cases had more than one recurrence. Recent evidence suggests radiotherapy, which has been reserved for inoperable lesions, may be of value as an adjunct to primary treatment. Limited local excision with adjunctive radiotherapy may decrease recurrence rate, minimize functional deficit, and improve cosmesis. Radical local resection (compartmental or amputation) may be avoidable. In children, amputation may not result in cure because of the multicentric behavior pattern and radiotherapy may lead to growth retardation. A shorter functional upper or lower limb is preferable to an amputation stump or a limb disfigured from radical excision.

Soft tissue sarcomas are uncommon malignancies, less than 10% of which arise on the distal upper extremities. Consequently, experience with treatments which preserve both the limb and its function is lacking for tumors in this region. Sixteen patients with sarcomas arising in the hand and wrist and one with an aggressive desmoid tumor were treated by combined modality therapy at the Massachusetts General Hospital. Two patients had wide resections for multiple recurrent lesions, 5 had excisional biopsies, and 9 had incomplete excisions to preserve anatomic structures of the hand. One patient refused an amputation and had no surgery. Sarcoma patients were given postoperative radiation with a dose range of 50.2 to 69 Gy (median 68 Gy). The desmoid tumor received 44 Gy. A shrinking field technique with customized castings and cerrobend blocks was used to assure precision and minimize treatment volumes. Chemotherapy was reserved for metastatic disease. Local control was achieved in 14 patients who received combined modality treatment (87%), with a follow-up 1-12 years (median 33 months). Two of the three patients with local failures subsequently obtained a local control after salvage surgery and radiation. Four patients developed metastases, one with epitrochlear lymph node metastases was salvaged by amputation, the others died with lung disease 17, 37, and 111 months after treatment. Functional integrity of the limb was primarily dependent on the extent of surgical resection required. Among 12 patients with local and distant control, one patient (who had multiple wide resections of an extensive desmoid tumor preceding irradiation) lost over 50% use of her limb, but no patients required amputation for edema or pain control. Ten of the 12 patients with local and distant control had less than a 25% decrement in limb function and had no pain or edema associated with normal use of their hand. We conclude that for selected patients with sarcomas of the distal upper extremity, combined modality therapy consisting of conservative resection and careful radiation therapy is a viable alternative to amputation.

The criteria for recommending an operant conditioning program for a patient with chronic pain include definable pain behavior. A thorough investigation of all organic factors that may contribute to pain is usually made prior to such treatment. This report describes a patient with chronic pain and mild cognitive deficits related to a truck accident who insidiously developed an extra-abdominal desmoid tumor. Desmoid tumors, which may develop after trauma, are associated with incidental connective tissue anomalies. They can be initially mistaken for fibrocytic nodules because they have a distribution similar to that in fibromyalgia. This patient's painful tumor was diagnosed while he was participating in a remobilization program. Subsequent resection and irradiation adversely affected rehabilitation goals and reinforced the patient's conviction that all his complaints were organically based.

A patient is described with Gardner's syndrome manifested initially by an extra-abdominal desmoid which was resected. The case was complicated by metastatic adenocarcinoma of the colon and recurrence of several large painful desmoid lesions. In view of the predilection of desmoids to occur in women in their childbearing years, it was decided to treat these painful lesions with an anti-estrogen, tamoxifen (20 mg orally, four times daily). This therapy led to a complete relief of pain within 1 week and a progressive decrease in the size of the desmoid tumors to less than 50% of their initial volume by the end of the second week. Unfortunately, the patient's metastatic adenocarcinoma progressed and was complicated by sepsis leading to her death. This case suggests that the growth of desmoid tumors is under hormonal influence, a suggestion which deserves further investigation.

Inflammatory myofibroblastic tumor (IMT) or inflammatory pseudotumor is a spindle cell proliferation of disputed nosology, with a distinctive fibroinflammatory and even pseudosarcomatous appearance. Although the lung is the best known and most common site, inflammatory myofibroblastic tumor occurs in diverse extrapulmonary locations. We report our experience with 84 cases occurring in the soft tissues and viscera of 48 female patients and 36 male patients between the ages of 3 months and 46 years (mean, 9.7 years; median, 9 years). A mass, fever, weight loss, pain, and site-specific symptoms were the presenting complaints. Laboratory abnormalities included anemia, thrombocytosis, polyclonal hypergammaglobulinemia, and elevated erythrocyte sedimentation rate. Sites of involvement included abdomen, retroperitoneum, or pelvis (61 cases); head and neck, including upper respiratory tract (12 cases); trunk (8 cases); and extremities (3 cases). The lesions ranged in size from 1 to 17 cm (mean, 6.4; median, 6.0). Excision was performed in 69 cases. Eight had biopsy only. Five patients received chemotherapy or radiation in addition to undergoing biopsy or resection as initial treatment. Sixteen patients had multinodular masses involving one region. Clinical follow-up in 53 cases revealed that 44 patients were alive with no evidence of disease, four were alive with IMT, and five were dead. Thirteen patients had one or more recurrences at intervals of 1-24 months (mean, 6 months; median, 10 months). No distant metastases were documented. The five patients who died had complications either due to the location of the lesion (heart, peritoneum, retroperitoneum, or mesentery) or related to treatment (lymphoproliferative disorder following hepatic transplantation; sepsis following wound infection). The abdominal masses were the largest. All tumors were firm and white with infiltrative borders and focal myxoid change. Three basic histologic patterns were recognized: (a) myxoid, vascular, and inflammatory areas resembling nodular fasciitis; (b) compact spindle cells with intermingled inflammatory cells (lymphocytes, plasma cells, and eosinophils) resembling fibrous histiocytoma; and (c) dense plate-like collagen resembling a desmoid or scar. Immunohistochemistry demonstrated positivity for vimentin, muscle-specific actin, smooth muscle actin, and cytokeratin consistent with myofibroblasts. Based on this series, inflammatory myofibroblastic tumor is a benign, nonmetastasizing proliferation of myofibroblasts with a potential for recurrence and persistent local growth, similar in some respects to the fibromatoses.

Abdominal desmoid tumor or fibromatosis is a benign non-urological connective tumor which can be mistaken for a urological tumor due to its localization (generally in muscles and aponeurosis of the abdominal wall). It is locally invasive and potentially recurrent. We report on a 53-year-old male with abdominal desmoid tumor whose only symptom was pain. The clinical diagnosis was corroborated by the US and CT findings and confirmed by anatomopathological findings. Wide local surgical excision is the treatment of choice since hormone therapy, radiotherapy and chemotherapy achieved scant results.
