Objectives Most cases of pediatric scalp and skull masses are either congenital or developmental tumors or diseases, and in many patients, these lesions are accompanied by intracranial extension. Past studies pertaining to these conditions are few, and thus clinical information is as yet inadequate. Materials and methods The authors present 75 pediatric patients with 77 cases of surgically treated scalp and skull masses. The most common pathologic condition was Langerhans cell histiocytosis, followed by epidermal cysts, epidermoid and dermoids, scalp hemangiomas, and neurofibromas, in descending order. Intracranial extension was observed in three cases (4%); two cases were malignant tumors that were skull metastasis of a neuroblastoma and a lymphoma, and one case was encephalocele. Lesions followed up because of possible recurrence were 15 cases of Langerhans cell histiocytosis, eight cases of epidermoid and dermoids, two cases of malignant tumors, and one case each of desmoplastic fibroma, myxoma, fibroid dysplasia, and neurofibroma, totaling 29 cases (39%). Conclusion Although the overall incidence of intracranial extension of pediatric scalp and skull masses is very low and the presence of a malignant tumor or metastatic tumor presenting as a scalp and skull mass is rare, such masses enlarge as time progresses, and there exists a possibility of recurrent disease. Therefore, it is suggested that early surgical resection will afford favorable prognosis for the patients, and meticulous follow-up is necessary in some conditions.

BACKGROUND Scalp lesions are frequently encountered in clinical practice. Fine‐needle aspiration cytology (FNAC) can characterize most of these lesions; however, there is little published work on cytology of scalp lesions. METHODS Records of all the patients subjected to FNAC from January 2011 to August 2016 were retrieved from the archives of the Cytopathology section of our Institute. Out of the 71 852 cases reviewed, 896 patients, who presented with palpable scalp lesions, were included in the study. Aspirates were obtained with a 23‐gauge needle attached to a 10 mL disposable plastic syringe. May–Grünwald–Giemsa stained and Pap stained slides were prepared. Special stains and immunocytochemical analysis were done when necessary. RESULTS Out of the 896 cases of aspirates from scalp lesions, 155 (17.2%) aspirates were found to be inadequate for diagnosis. One hundred and fifty‐seven (21%) out of 741 adequate aspirates showed features of inflammatory or reactive pathology comprising of abscesses (57), cystic lesions (24), tubercular lesions (16), and reactive lymphadenopathy (66). Four hundred and fifteen (56%) aspirates revealed a tumor‐like etiology comprising of epidermal cyst (395), sebaceous cyst (4), dermoid cyst (1), calcinosis (7), vascular malformation (7), hematoma (5), and juvenile xanthogranulomatous lesion (1). Tumorous lesions formed 22.3% of the aspirates. Of these, 7 cases (4.2%) were of metastases to the scalp. CONCLUSION In a developing country, FNAC is a useful and cost‐effective investigation for the diagnosis of a wide spectrum of scalp lesions. It allows rapid diagnosis and permits timely intervention thereby preventing complications due to delay in diagnosis.
