ABSTRACT
Subungual osteochondroma (SO) is an infrequent and non-malignant bone tumour of the distal phalanx, especially prominent in paediatric populations. The aim of this research was to describe a case series of paediatric feet with SO which received surgical treatments. The secondary purpose was to compare these descriptive data by sex distribution. METHODS: Twenty-three paediatric feet with SO confirmed by clinical or radiological features received surgical treatment. Socio-demographic (age, sex, height, weight and BMI) and clinical features (side, location, tumour or pain presence, and nail lift before surgery, as well as recurrence and adverse effects at one month after intervention) were reported. RESULTS: Regarding clinical features before intervention, the most frequent locations of SO were the first toe (86.8%) and the right lower limb (56.5%). In addition, the presence of the tumour, pain and nail lift showed a prevalence of 91.3%, 69.5% and 47% of the study sample, respectively. Considering clinical features at one month after intervention, the most frequent adverse effect was the pain presence (69.5%). In addition, one case (4.4%) presented ulceration. Only one patient (4.4%) suffered from recurrence with a new tumour. There were not statistically significant differences by sex distribution (p > 0.05). CONCLUSIONS: This novel study showed that surgery treatment for SO in paediatric populations presented a very low recurrence degree with minor adverse effects and without differences by sex distribution. Thus, further randomized clinical trials should be carried out in order to determine the effectiveness of this intervention in this special population.
ABSTRACT
A 6-month-old Caucasian baby is described with a postaxial polydactyly of the letf foot. Radiographic examination revealed the accessory digit was composed of soft tissue, some with a tiny osseous element, originated from around the metatarsophalangeal joint, defined by floating type (FT). The parents had consistent difficulty putting shoes. We encountered an exceedingly rare presentation of FT, to our inspection, had neither been previously related in published studies. To the best of our knowledge, this represents the unusual case of congenital deformity lesion on the left foot to be reported in the medical literature.

A 5-year-old caucasian child is described with a congenital melanocytic periungual and subungual nevus on the right second toe. Histopathologic examination revealed a junctional nevus. Congenital subungual nevi in this location are rare. To the best of our knowledge, this represents the first case of lesion on the right second toe to be reported in the literature.

El propósito de este artículo es mostrar la opción terapéutica adoptada en un caso clínico de una malformación congénita de duplicidad ungueal; a la vez que mostrar una revisión de las afecciones, que al igual que la duplicidad ungueal, cursan con la aparición de dos uñas completas en un mismo dedo.Para realizar un diagnóstico diferencial entre la polisindáctilia, la polioniquia y la duplicidad ungueal el examen de la estructura ósea resulta imprescindible, la aparición de elementos óseos duplicados en todo el dedo, caracterizaría la polisindactília; la existencia de falanges distales bífidas o bipartitas sería característico de la polioniquia y la ausencia de elementos óseos supernumerarios el determinante de la duplicidad ungueal, si bien muchos autores denominan la aparición de uñas supernumerarias polioniquia sin realizar diferenciación. Por ello mostramos el análisis de las radiografías realizadas en el caso clínico, que resultaron concluyentes para el diagnóstico definitivo. La aparición de dos unidades ungueales completas, lateralizadas hacía los bordes medial y lateral del segundo dedo del pie derecho, producía una deformidad en el dedo desde el nacimiento. A pesar de que el paciente asistió por primera vez a consulta a los 15 meses de edad, optamos por esperar 6 meses para analizar si alguna de las dos unidades ungueales adoptaba una posición dorsal y un mayor tamaño para realizar las funciones biomecánicas de la uña. El buen resultado en un caso tratado con anterioridad, en el que existía la misma deformidad, fue determinante para realizar una resección total de la uña situada en el borde lateral y al mismo tiempo realizar una resección de los tejidos circundantes, que dotaban al dedo de mayor volumen en la zona distal. Los objetivos de la intervención eran restablecer la función biomecánica de la uña, posibilitar el uso de calzado normal, mejorar la estética del pie y prevenir futuras afecciones. El resultado de la intervención quirúrgica fue satisfactorio, sin embargo la lateralización hacia medial de la única uña existente y la ausencia de osificación de la falange distal nos hacen prever la necesidad de aplicación de tratamientos quiropodológicos y ortopodológicos en un futuro (AU)
