Abstract

A 47-year-old female of African origin, presented with history of a growing lump on the sole of her right foot. She normally lives in the UK, but has been visiting an African country in the last few years. Physical examination showed an isolated nodular lesion on the sole of her right foot, at the instep with intact skin, and no sinus formation. The working diagnosis was a plantar fibroma. The patient was otherwise fit and well and was not on steroids or other medications. Physical examination revealed an isolated lump on the sole of her foot, with no other findings. Differential diagnoses considered include plantar fibroma, inter-metatarsal neuroma, subcutaneous lipoma, plantar fasciitis, aspergillosis, ganglion and warts among others. She had Ultrasound and later excision biopsy followed by histology which confirmed fungal Mycetoma. She made a recovery without any additional treatment and had no recurrence after two years of follow-up.

Highlights

Mycetoma is an uncommon condition that can affect any part of the body including the foot (Pedal Mycetoma)
Physical examination revealed an isolated lump on the sole of her foot, but other systemic examinations were negative for any findings
Haematoxylin-eosin staining of the biopsy specimen revealed the presence of fungal grains, and the appearances of the lesion were those of Mycetoma (Figures 3-6)

Summary

Introduction

Mycetoma is an uncommon condition that can affect any part of the body including the foot (Pedal Mycetoma). Majority of the literature regarding this condition is old and mostly comes from these developing countries, but Messoudi et al recently published a series of fifteen cases of Madura foot in Morocco [2]. A 47-year-old female of African origin, presented with two year history of a growing lump on the sole of her right foot.
