We report a case of an unusual and unsuspected chronic infection creating a soft-tissue mass in the foot of a 35-year-old woman. The causative agent, Mycobacterium gordonae, is usually encountered as a laboratory contaminant. Only rarely does it manifest as a clinical infection. The patient’s presumed predisposing risk factor was a history of barefoot gardening. An iatrogenic source, corticosteroid injections, was also considered.

Closed rupture of the extensor hallucis longus (EHL) tendon is rare, with most cases caused by either direct penetrating trauma or predisposing factors such as corticosteroid injection and iatrogenic trauma incidences. Almost all of the previous case reports have reported on rupture of the EHL tendon rather than the EHL muscle. In this report, we highlight an unusual clinical presentation of a rupture of the EHL muscle and discuss its predisposing factors. This patient was a taekwondo athlete with EHL muscle rupture secondary to repetitive overuse without any underlying systemic or local predisposing factors or direct trauma. Fifteen months after successful surgical treatment, he became fully functional again as an elite taekwondo athlete.
Triamcinolone acetonide is a synthetic glucocorticoid used to treat numerous acute and chronic inflammatory conditions. The various side effects of this drug from parenteral administration are well documented in the literature. In this study, three patients present with a rare side effect of violaceous dermal pigmentation. To the best of the authors' knowledge, this finding is rarely presented in the current literature. The purpose of this study is to provide awareness of a less-documented, delayed side effect from triamcinolone acetonide administration. Although all patients presenting in this study had a known history of autoimmune disease (eg, lupus, psoriatic arthritis) further research is needed to suggest a possible association between dermal violaceous change and the use of triamcinolone.
Neurectomy for Bilateral Morton's Neuroma
A Case Report of a Male Patient
Morton's neuroma is a common condition that mainly affects middle-aged women, and many articles have addressed the surgical treatment of this condition. Previous reports have described bilateral neuroma excision in women but not in men. We report a rare case of bilateral neuromas in a male patient treated with simultaneous neurectomy.
Pedal Presentation of Superficial Acral Fibromyxoma
A Case Report
Superficial acral fibromyxoma is a benign and slow-growing solitary soft-tissue neoplasm. Since being described in 2001, more than 100 cases of superficial acral fibromyxoma on the foot have been reported worldwide, none of which have been reported in the podiatric medical literature. Only nine cases of superficial acral fibromyxoma have been reported with presentation on the plantar heel. We report an unusual case of a 47-year-old Jamaican woman with a painful, erythematous nodule on her right heel that was diagnosed as superficial acral fibromyxoma.
Diagnosis and treatment of longitudinal tears of the tibialis anterior tendon are not well documented in the surgical literature. Described here is successful primary surgical repair of a longitudinally torn tibialis anterior tendon in a 60-year-old woman. (J Am Podiatr Med Assoc 95(4): 390–393, 2005)
There are few documented reports of arteriovenous malformations in the extremities, and even fewer specifically in the foot. Most of the documented cases in the foot present surgical treatments, and there is limited information on the nonsurgical approach. A brief review of the surgical approach to arteriovenous malformations in the foot and hand is presented first, followed by a case report of the nonsurgical treatment of an arteriovenous malformation in the foot, which was initially diagnosed incorrectly.
Background
Recently, transcranial direct current stimulation (tDCS), a noninvasive brain stimulation technique, was proposed as a suitable method for the treatment of several chronic pain syndromes. We describe a case of severe heel pain in a diabetic patient with plantar fasciitis successfully treated with tDCS.
Methods
The present study investigated whether tDCS treatment could reduce pain and pain-related anxiety in a 65-year-old diabetic man affected by treatment-resistant right heel pain due to plantar fasciitis. The patient underwent five tDCS treatment sessions on 5 consecutive days. Each session consisted of 20-min anodal tDCS over the left primary motor cortex leg area.
Results
The neurostimulation protocol induced a decrease in pain intensity and pain-related anxiety that outlasted the stimulation (1 week). Furthermore, the patient stopped the intake of opioid medication.
Conclusions
Therapeutic neuromodulation with tDCS may represent an alternative option for treating severe lower-extremity pain.
Granular cell tumor of peripheral nerves is extremely rare. We present the case of a patient with a well-capsulated intraneural granular cell tumor involving the posterior tibial nerve, who presented with chronic heel pain mimicking plantar fasciitis. Magnetic resonance imaging revealed a well-defined intraneural soft-tissue mass within the substance of the posterior tibial nerve. Histopathologic examination showed a granular cell tumor, which is extremley rare in the peripheral nerves. Heel pain is one of the common conditions handled by physicians, podiatrists, and orthopedic surgeons. Posterior tibial nerve lesions at the leg should be kept in mind in the differential diagnosis of patients with persistent heel and foot pain. Magnetic resonance imaging is a useful method in the anatomical evaluation of focal intraneural lesions. (J Am Podiatr Med Assoc 99(3): 254–257, 2009)
Synovial chondromatosis is a rare, generally benign condition characterized by the formation of multiple cartilaginous nodules in the synovium of joints and occasionally on the tendon sheath or bursae. If the nodules are intra-articular, the condition is referred to as synovial chondromatosis; if extra-articular, tenosynovial chondromatosis. This space-occupying lesion can lead to chronic pain and limit the function of involved joints. We report a case of synovial chondromatosis involving the subtalar joint and tenosynovial chondromatosis involving the posterior ankle and review current definitions of this uncommon lower-extremity condition.
